[gentoo-science] File collision with mpich under empi

[marco restelli]

Hi,
I have installed mpich (sys-cluster/mpich-3.1.4-r1, with uses cxx,
fortran, mpi-threads, romio, -doc, -threads) and I would also like
having the same MPI implementation under "eselect mpi", using empi as
described here:

https://wiki.gentoo.org/wiki/Empi

The problem is that if I do

/usr/bin/empi --create --class mpi-mpich sys-cluster/mpich

I see the following file collisions:

* Detected file collision(s):
*
* /usr/share/doc/mpich-3.1.4-r1/README.bz2
* /usr/share/doc/mpich-3.1.4-r1/README.envvar.bz2
* /usr/share/doc/mpich-3.1.4-r1/CHANGES.bz2

Removing those 3 files fixes the problem, until the next emerge.
