I got it to work after playing around 'patch -p X' with
a few different variants of X.

Unfortunately, there are still a large number of failures.

This is due to not linking in libpthread.  On FreeBSD, to
include pthread, one needs to add the -pthread option or
have a spec file that magically includes or do whatever
gomp does.  With -fopenmp, -pthread is included.  Here's
an example:
