We no longer want to have patches that contain the package version in
their filename.

Any reason not to package the most recent version available? Are there
incompatibilities between 5.1.118 and 5.2.121 that makes 5.2.121
unusable for zeromq?

Are we sure that pgm_unaligned_pointers=yes will be valid on all
architectures?

Rather than hardcoding this, I would prefer if it was possible to pass
a variable in the configure script environment to tell the result of
this test. We could then maybe have a chance to upstream the patch.

Strange, the project is called openpgm but the tarball is named libpgm?
Usually, we try to use the upstream name, but here it's unclear if we
should choose libpgm or openpgm. Does the openpgm projects delivers
something else than libpgm?

Not needed if it's empty.

You should also add the OPENPGM_LICENSE and OPENPGM_LICENSE_FILES
variables.

Since the source code comes as a tarball, it's uncommon to have to do
an autoreconf. Could you add a comment right before this line that
explains why it is needed?

Have you tried to replace this post extract fix by:

OPENPGM_SUBDIR = openpgm/pgm/

 ?

Thanks,
