Description Michal Jaegermann 2018-01-12 02:50:06 UTC 
Description of problem:

With mpich package installed 'man' is loosing ability to display any manual pages other than located in /usr/share/man/mpich-x86_64/ tree.  Run 'man -d man' and see for yourself.

The culprit is the following line from /etc/modulefiles/mpi/mpich-x86_64

prepend-path  MANPATH       /usr/share/man/mpich-x86_64

The issue is that by default MANPATH is not set and 'man' relies on a configuration in /etc/man_db.conf. With the above line mpich sets unconditionally MANPATH to /usr/share/man/mpich-x86_64 and hilarity ensues.

The cure is simple.  Replace the faulty line above with

prepend-path  MANPATH       :/usr/share/man/mpich-x86_64

As documented this first searches "regular" directories as configured in /etc/man_db.conf followed by mpich specific stuff.
Putting ':' at the line end does not work!

Version-Release number of selected component (if applicable):
mpich-3.2.1-2.fc28.x86_64 and likely others

How reproducible:
always

Additional info:

Although PATH so far is set hence a line

prepend-path  PATH          /usr/lib64/mpich/bin

so far does not breaks the whole system quite thoroughly, lines

prepend-path  LD_LIBRARY_PATH /usr/lib64/mpich/lib
prepend-path  PKG_CONFIG_PATH /usr/lib64/mpich/lib/pkgconfig

look like have a serious potential for a mischief.  In particular there exist directories /usr/lib64/pkgconfig/ and /usr/share/pkgconfig/.  Are these not good enough?
Comment 1 Fedora End Of Life 2018-02-20 15:21:45 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.
Comment 2 Michal Jaegermann 2018-03-29 22:24:39 UTC 
An update of a rawhide installation, which brings in mpich-3.2.1-3.fc28.x86_64, breaks MANPATH once again; precisely as described in the original report from 2018-01-11.
Comment 3 Ankur Sinha (FranciscoD) 2018-04-04 07:39:42 UTC 
I see the same issue here on a F28 beta system. When mpi/openmpi-x86_64 is loaded, the MANPATH shows:

$ echo $MANPATH
/usr/share/man/openmpi-x86_64


and all the standard man pages are inaccessible.
