John,

thanks for fixing this!

I followed your advice and switched to Python 2 for now.

Now the ran into this error … the doxygen build fails with a compiler error:
https://gist.github.com/cdeil/3070715137ac799fcd41 <https://gist.github.com/cdeil/3070715137ac799fcd41>

I do have doxygen 1.8.7 from Macports at /opt/local/bin/doxygen and on my PATH, is it really useful to build a separate one from source?

Another issue I noticed is that it’s not possible to blow away the LSST software folder with rm -r … I think the reason is that I don’t have write permissions for the eups/python folder.
Can you change this so that I don’t have to fiddle with chmod or sudo?

$ rm -r eups
rm: eups/python/eups/__init__.py: Permission denied
$ ls -lh eups/
total 80
