It looks like the irix compiler is a little picky about order
of flags, or perhaps it doesn't like to have -lmpi during the
compile stage.

In any case, I simply worked around it by temporarily adding the LDADD
flag to the LIBS variable when I try to link the MPI program. Don't
know why it's not added by default in autoconf, but now it should work.

I'll include it in a 3.0.1 revision in a couple of days, but I've put a
new version of the configure file at ftp://ftp.gromacs.org/pub/patches
in the meantime.
You might have to make it executable after downloading it!

Erik

(I'm working on the GMXRC script to, should have that fixed in 1-2 hrs :-)
