[WIP] Debug R doc build failure

[TomAugspurger]

#20648

[TomAugspurger]

The packages built by anaconda include compiler flags (-fPIC) that should make this error impossible. Seeing if (temporarily) excluding conda-forge packages fixes things.

Hello @TomAugspurger! Thanks for updating the PR.

• In the file doc/source/conf.py, following are the PEP8 issues :

Hmm, still trying to get a local reproducer, but https://travis-ci.org/pandas-dev/pandas/jobs/371582150#L2705 managed to import rpy2, I guess since it was imported early enough :/

It sounds like either Travis' glibc is the bottleneck here. We won't be able to do much to work around it unfortunately.

Thanks for looking into this.
Temporary / definite workaround would be just remove that doc section, or to convert it to static code-blocks.

[TomAugspurger]

Yeah. I'm able to build things locally, so I'm not too worried about it delaying the relase.
