Description of problem: The mpich package installs its man pages under a non-arch specific directory: /usr/share/man/mpich/man1 whereas the guidelines[1] state: As include files and manual pages are bound to overlap between different MPI implementations, they MUST also placed outside normal directories. It is possible that some man pages or include files (either those of the MPI compiler itself or of some MPI software installed in the compiler's directory) are architecture specific (e.g. a definition on a 32-bit arch differs from that on a 64-bit arch), the directories that MUST be used are as follows: Man pages %{_mandir}/%{name}-%{_arch}%{?_cc_name_suffix}/ The openmpi package gets this right, for reference. So, the man pages need to be moved, and the environment module file updated accordingly. [1] https://fedoraproject.org/wiki/Packaging:MPI
I don't think arch-specific man pages make much sense, but since the guidelines state "MUST", I'll just follow that.
