You should probably fix this rpmlint output:
E: beryl-dbus zero-length /usr/share/doc/beryl-dbus-0.1.2/AUTHORS

Done, along with switching over to using upstream tarball.

http://wilsonet.com/packages/beryl/beryl-dbus-0.1.2-2.fc6.src.rpm

Well,
1. From http://fedoraproject.org/wiki/Packaging/ReviewGuidelines :

* BuildRequires:
  - Well, too much redundant BuildRequires (I don't like this...)
    All needed are:
-------------------------------------------------
beryl-core-devel >= %{version}
dbus-devel
++++++++
libXcomposite-devel
libXdamage-devel
libSM-devel
libpng-devel
libXext-devel
libXinerama-devel
startup-notification-devel
libXrandr-devel
libXrender-devel
++++++++
-------------------------------------------------
    Actually these dependency finally 98 minimal build enviroment + 
    42 other package (tol: 140), while your original package tries
    to install 276 package.

NOTE: The packages between +(plus) symbols, i.e.
-------------------------------------------------
libXcomposite-devel
libXdamage-devel
libSM-devel
libpng-devel
libXext-devel
libXinerama-devel
startup-notification-devel
libXrandr-devel
libXrender-devel
-------------------------------------------------
   should be required by beryl-core-devel (check /usr/lib/pkgconfig/beryl.pc)
   so beryl-core-devel package should be fixed. After that this package
   should only require:
--------------------------------------------------
beryl-core-devel >= %{version}
dbus-devel
--------------------------------------------------
   for BuildRequires (I want to check this again so that would you
   fix beryl-core-devel first?)

* Requires:
  - dbus
    This is not necessary as libraries' dependency automatically pulls this.
    

2. Other things I have noticed :
* %doc
  - Well /usr/share/doc/beryl-dbus-0.1.2/ChangeLog says:
-------------------------------------------------
see debian/changelog
-------------------------------------------------
    ... however, where is debian/changelog?

99. For other packages:
99-A For beryl-core package:
* Well, rpmlint is not silent.
--------------------------------------------------
W: beryl-core undefined-non-weak-symbol /usr/lib/libberylsettings.so.0.0.0 g_free
W: beryl-core undefined-non-weak-symbol /usr/lib/libberylsettings.so.0.0.0 g_free
W: beryl-core undefined-non-weak-symbol /usr/lib/libberylsettings.so.0.0.0
g_slist_remove
W: beryl-core undefined-non-weak-symbol /usr/lib/libberylsettings.so.0.0.0
g_mkdir_with_parents
W: beryl-core undefined-non-weak-symbol /usr/lib/libberylsettings.so.0.0.0
g_key_file_has_key
....(too much)
---------------------------------------------------
  Perhaps linking against glib or something else is not correct.

Well, it seems that you write many unneeded BuildRequires on
beryl-related packages, which should be fixed.

Thanks much for the leg-work! I'll work on cleaning that all up. I think I
copied over the beryl-core spec to the first sub-package, and largely left the
BR in place, should have trimmed them then. I'll fix up beryl-core-devel's
dependencies first up, then work on the rest...

Okay, I've got a new build of beryl-dbus that has only BR: beryl-core-devel and
dbus-devel, and it builds perfectly in mock, with an updated beryl-core that
adds all the other bits as requirements of beryl-core-devel. I've also deleted
the ChangeLog file from %doc, I don't see debian/changelog anywhere in the
tarball (this project is, um, a little lax on docs...). I haven't yet pushed a
build of that updated beryl-core version through Extras though, as I want to
trim the BR on all the othe beryl bits first.

http://wilsonet.com/packages/beryl/beryl-dbus-0.1.2-3.fc6.src.rpm

Okay.
-----------------------------------------------
   This package (beryl-dbus) is APPROVED by me.
-----------------------------------------------

Two comments.
1. Requires: dbus
   This is not necessary because this package (beryl-dbus) requires
   libdbus-1.so.3 and this adds dbus dependency automatically.
2. For beryl-core package:
   /usr/lib/libberylsettings.so.0.0.0 contains lots of undefined non-weak
   symbols (as said above).

Done for the version I'll import once cvs is resurrected. Thank you!

Looking into it now...
