Dear Guix:

I am pleased to submit a patch that adds OpenMolcas to Guix. Also
included in this submission is a new variable called `openblas-ilp64'
which OpenMolcas needs to compile and run.

I would like to point out that I have already submitted the
openblas-ilp64 patch to the list for approval, and I am aware that this
submission may need to be revised to include just the program of
immediate interest.

Best regards,
Eric
