MPE currently does not have shared library support yet.
If you really need libmpe.so, you can build MPE as a standalone
package for MPICH2 with CFLAGS set to -fPIC.  You can then
use the .o files (from libmpe.a) and build your own libmpe.so.

To build typical MPI executable, you can mix libmpich.so and libmpe.a.

What .so file you are building that needs libmpe.so ?
