Hmm, even libtool 1.5.26 should be detecting mpicc as gcc but apparently
it isn't.  You could look in config.log to find out why.  I'd really
really suggest using a newer Libtool though, 2.4 is the current version,
and I'm not eager to debug issues in the 1.5 branch (which has been dead
for almost three years now) any more.

Thanks,
