[MPICH] Application Link Error when using mpich2-1.0.6 in smpd mode

[Cavey, Lester]

I don't have a libssl or a libcrypt on my linux machine, even when I
build mpich2-1.0.6 configured in smpd mode.  Are you saying that you all
will add that feature, and then I will be able to link to those
libraries?  If so, could you let me know when that feature gets added?

Thanks,
Lester

It looks like a missing '-lssl' or '-lcrypt'.

Looks like a bug in our configure script (didn't add the necessary
libraries to mpicc or mpif90).

If you add -lssl or -lcrypt to your link step, and the error goes
away, then we know what we need to fix.
