Amazing what a kick in the pants and boredom will do.  I hacked up some 
support for bproc-4 based on previous e-mails from Erik and Greg.  
Testing is at the "it compiled without warnings" stage, so this might 
take a couple of tries to get right.  Let me know how it goes.

I've attached a patch against our current SVN tree.  You will need to 
check out the trunk, apply the attached patch, run the autogen.sh 
script, then the usual configure ; make ; make install.  More detailed 
instructions, including requirements for Autoconf, Automake, and 
Libtool can be found on our web page at:

   http://www.lam-mpi.org/svn/

If anyone wants to try this out, but can't get subversion or the 
Autotools to work, let me know and I'll build a tarball and post it 
somewhere.

PS. In theory, Myrinet/GM and InfiniBand support should work just fine 
with the LAM trunk and BProc.  If you have such a cluster, let me know 
how it goes - I don't think anyone has tried it before.
