I struggled with this just the other day. I could not get the build system to install the man pages despite many attempts. I gave up and just did a manual install by copying the man subdirectory of the source into my install directory. In any case, I don't know why "man mpich" should work. What would that tell you? Try "man mpicc" or "man MPI_Barrier", for example. Perhaps with "man mpich" you are looking for something like the following?

mpichversion MPICH Version: 3.1b1 MPICH Release date: Thu Aug 8 10:41:27 CDT 2013 MPICH Device: ch3:nemesis MPICH configure: CC=clang CXX=clang++ FC=/bin/false --disable-fc --disable-f77 --enable-threads --enable-g --with-pm=hydra --prefix=/opt/mpich/3.1b1/clang MPICH CC: clang -g -O2 MPICH CXX: clang++ -g -O2 MPICH F77: no -g MPICH FC: no -g

How do I set the MANPATH mpich-3.0.4 on Debian Wheezy? The installation location is /opt/mpich. I tried in ~/.bashrc: MANPATH = /opt/mpich/share/man:$MANPATH export MANPATH but not work. I call 'man mpich', or is not that what you call the man of mpich? I researched and not found.

However, PATH=/opt/mpich/bin:$PATH export PATH worked.
