Hi,
You have a type 

rm -rf %{_buildroot}

should of course be 

rm -rf %{buildroot}


Otherwise this looks like a text book rubygem package as described on 
http://fedoraproject.org/wiki/Packaging:Ruby 

I have issues with the ruby guidelines but they are what they are so we follow them:

Checksums match.

$ md5sum systemu-2.4.1.gem ../SOURCES/systemu-2.4.1.gem 
c95eb1dd231cac73b11224a9d3ee35c2  systemu-2.4.1.gem
c95eb1dd231cac73b11224a9d3ee35c2  ../SOURCES/systemu-2.4.1.gem


License is marked with 'Ruby or GPLv2' and this is clearly correct.

same as Ruby's

http://www.ruby-lang.org/en/LICENSE.txt
 
is contained within the LICENSE.txt file.

rubygem-systemu.noarch: W: spelling-error Summary(en_US) stdout -> stout, std out, std-out
rubygem-systemu.noarch: W: spelling-error Summary(en_US) stderr -> std err, std-err, stander
rubygem-systemu.noarch: W: spelling-error Summary(en_US) pid -> peed, dip, pud

which are all fine.

rubygem-systemu.noarch: W: non-standard-group Unspecified

rubygem-systemu.src: W: non-standard-group Unspecified
rubygem-systemu.src: W: no-cleaning-of-buildroot %install
2 packages and 1 specfiles checked; 0 errors, 16 warnings.


So please add a group and correct the _buildroot macro and I think it is there.

Steve.

Spec URL: http://jcollie.fedorapeople.org/rubygem-systemu.spec
SRPM URL: http://jcollie.fedorapeople.org/rubygem-systemu-2.4.1-2.fc16.src.rpm

OK, here's a new version that should fix the problems with the macro and the group.  For some reason though this doesn't build for me on EPEL5, I get a buffer overflow in ruby.

EPEL5 can come later if needed of course .

APPROVED.

New Package SCM Request
=======================
Package Name: rubygem-systemu
Short Description: Universal capture of stdout and stderr and handling of child process pid
Owners: jcollie
Branches: f16 f15 el5 el6
InitialCC:

Already exists, unretired, please take ownership of f15 and devel in
pkgdb, then file package change for f16 branch.  EL-5 and 6 exist and are
owned.

Well, blow me down... I guess I need to search pkgdb rather than relying on a yum search.

Package Name: rubygem-systemu
New Branches: f16
Owners: jcollie
InitialCC:

none found

=== Final Notes ===
/usr/lib/ruby/gems/1.8/cache/ is not owned by the package, is used and provided by the rubygem rpm which is present as dependency. 
I could not test the correct functioning of the package nor if it builds on all architecture. As it is a noarch package I don't see a 
reason why it should not

Jeffrey et. al.:

This review is almost a year old with no import into Fedora/EPEL even though it's been approved. Can we import it? I need it to get bz#823344 working.

I'm happy to take ownership if you don't want to maintain it now.

Julian, I have no interest in rubygem-systemu anymore. I've gone ahead and orphaned the package in pkgdb:
