Actually, BLACS and PCSDP compile fine here (w/ Open MPI-1.2.8)

The libtool files (.la) will not help You in this case.
If You want to link against the Open MPI's C++ Interface, You'd just need to
pass
   mpif77 .... -L/home/openmpi_123/lib -lmpi_cxx
The compiler-wrapper mpif77 actually includes the library-search path (-L):
Use mpif77 -showme:
 gfortran -I/opt/openmpi-1.2.8/include -L/opt/openmpi-1.2.8/lib -lmpi_f77 ...

These are the libtool '.la' files, which help when linking using libtool.
The lib-library however should contain the shard-library files (libmpi.so*
libmpi_cxx.so*), right?

So You can link against the shared libraries.

With best regards,
Rainer
