[Debian-science-sagemath] Tests timing out

Yes, I am getting this too, I documented it a bit in README.Debian. It is R related, but that package itself has not been upgraded since June.

To debug, you can: Give --verbose to see which test case it's hanging on. Running R manually works. Run the example manually inside ./sage and press Ctrl-C to get a backtrace.

I haven't yet looked into this further, so I don't have other ideas just yet.

BTW I have changed the packaging so it now installs stuff in debian/tmp. I think I fixed all the path issues, and now there are no new test failures. So you can "git pull" and try it out. It will invalidate your ccache though. Also to run the tests directly you will need to set SAGE_LOCAL and PYTHONPATH, as documented in README.Debian.
