Re: [PATCH 4/4] gnu: matplotlib: Add gtk3 backends.

[Ludovic Courtès]

I found that “guix build python2-matplotlib -n” triggers a seemingly
infinite loop (either uses of ‘package-with-python2’ somehow introduce
cycles, or they lead to very large DAGs), which is what is causing Hydra
evaluation failures.

I tried reverting 25f9a0 but it doesn’t help.

Could you try to bisect it and revert or fix the problem?  If it turns
out to require more time, could you just comment out the offending parts
of python.scm so Hydra can resume?

Thanks in advance, and apologies for not noticing earlier!
