Hi Noel,

I figured out my mistake: There was obviously a mismatch in the way 
the MPICH2 libraries were compiled and what boost.mpi expected. 

I played around with the configure settings of both and aligned them
so that mpich2 was compiled with -fPIC as well as with dynamic libraries.

mpich2$./configure     --without-mpe     --disable-f77     --disable-f90    
\
--disable-f90modules     --disable-cxx     --disable-mpedbg    
--disable-devdebug  \
--disable-debug     --enable-fast     --enable-sharedlibs=gcc    
--with-device=ch3:nemesis 

accomplished it for some reason...

best wishes,

Michael
