I get the problems with custom decision function as well as without. Today
I downloaded a clean tarball 1.1a1r8626 and changed nothing. I simply
configure with

$ ./configure --prefix=/home/ckutzne/ompi1.1a1r8626-gcc331

Then make all install and that's it. I both tried gcc3.3.1 and gcc4.0.2.

Then I install MPE from mpe2.tar.gz with
 ./configure MPI_CC=/home/ckutzne/ompi1.1a1r8626-gcc331/bin/mpicc \
              CC=/usr/bin/gcc \
              MPI_F77=/home/ckutzne/ompi1.1a1r8626-gcc331/bin/mpif77 \
              F77=/usr/bin/gcc \
              --prefix=/home/ckutzne/mpe2-ompi1.1a1r8626-gcc331
    make
    make install
    make installcheck --> ok!

I did not set anything in an .mca conf file (do I have to?)
