I was compiling lam/mpi 7.1.1 with FC=xlf. All this part worked.
It is only after rebuilding pyMPI and trying it that I got into trouble,
i.e. got
$ ./pyMPI
dyld: ./pyMPI multiple definitions of symbol _Py_GetVersion
./pyMPI definition of _Py_GetVersion
/sw/lib/python2.3/config/libpython2.3.dylib(getversion.o) definition of
_Py_GetVersion
Trace/BPT trap
Since I could build and run pyMPI using lam/mpi 6.5.9
pre-compiled library, I am assuming that the issue might just be
related to options passed when configuring lam/mpi before
compiling it. Interestingly, the multiple definition of _Py_GetVersion
message, that is caught at run time using lam/mpi 7.1.1 (compiled
by myself), preceding the 'Trace/BPT trap' message, is caused at
link time when building pyMPI using the fink pre-compiled
lam/mpi 6.5.9. So, I am assuming that some flags used when
configuring before compiling the lam/mpi binary distributed through
fink caused mpicc to detect the multiple definition at link time but
somehow ignore it.
