If you're going to be using LAM with high performance computational code,
you more than likely want to use the native Sun compilers, not the GNU
compilers. I would recommend setting the following environment variables:
CC cc
CXX CC
FC f77
F77 f77
before running configure. LAM's configure script unfortunately has a GNU
bias in that it will automatically look for "gcc", "g++", and "g77" before
any other compilers unless you set these environment variables. Although
the GNU compilers are decent, the native Solaris compilers are better.

This name (muldi3) rings a distant bell... Doing some searches on the LAM
list, I see a few mails about this issue. For example, check out
http://www.lam-mpi.org/MailArchives/lam/msg02602.php.
This suggests that you may be mixing the Solaris and GNU compilers.
Indeed, in re-reading your above text, it looks like you used the GNU C
compiler (gcc) but the Solaris Fortran compiler (f77). This is almost
never a good idea. You might want to re-configure and recompile LAM and
see if that help.

This will likely be the same issue as #1.
