Hello,

I can reproduce the issue in schroot Sid environment on an amd64 box.
The Depends fields for the libraries is

${shlibs:Depends}, ${misc:Depends}

and it works fine except for mpich. Before to add it by hand, I want
to understand why dpkg-shlibdep does not make properly its job.

$ dpkg-shlibdeps debian/libtachyon-mpich-0/usr/lib/x86_64-linux-gnu/libtachyon-mpich-openmp.so.0

gives something interesting:

dpkg-shlibdeps: warning: /usr/lib/libmpich.so.12 has an unexpected SONAME (libmpi.so.20)
dpkg-shlibdeps: error: no dependency information found for /usr/lib/libmpich.so.12 (used by debian/libtachyon-mpich-0/usr/lib/x86_64-linux-gnu/libtachyon-mpich-openmp.so.0)

And, more interestingly,

ls -l /usr/lib/libmpich.so.12

gives

/usr/lib/libmpich.so.12 -> libmpi.so

libmpi.so coming from libopenmpi-dev while 


Installing only libmpich-dev on a fresh schroot gives similar output:
it looks as a mpich building error.



Thanks,
Jerome
