Description of problem:

With the system erfa 1.3.0, test_sidereal fails:

_____________ ERROR collecting astropy/time/tests/test_sidereal.py _____________

See https://github.com/astropy/astropy/pull/5466 for more details.

I'm proposing we build with the bundled erfa for now until this is resolved.

I'd also like to build with the bundled wcslib on EPEL.  See attached spec for details.  Although we do have an issue with an old scipy in EPEL at the moment.

Comment 3 Sergio Pascual 2016-11-21 22:40:21 UTC 
What version of erfa do you need in epel?
Comment 4 Orion Poplawski 2016-11-21 22:50:22 UTC 
Current erfa is fine in EPEL.  But with erfa 1.3.0, I think we should build with bundled erfa.

scipy is blocking updating astropy in EPEL though.

If you're okay with proposed spec I'll check that into master as build.
Comment 5 Sergio Pascual 2016-11-21 22:58:04 UTC 
You have uploaded a different spec, protobuf?

Ah, trying to do too many things at once again.  How about this?
Comment 7 Sergio Pascual 2016-11-21 23:27:42 UTC 
Fantastic, please go ahead and thank you
Comment 8 Orion Poplawski 2016-11-22 20:07:09 UTC 
ppc64 builds are still unstable unfortunately (due to bug #1394975), but managed to get a build to complete.
