btw the last time I had to do this I put the things that I would later revert in a specific commit so it was easy. (so create an issue to revert this when conda is fixed)

[TomAugspurger]

OK, hopefully that commit does it.

When I revert this, I'll add another commit that keeps

• fix the beautifulsoup4 package name
• fix the bzip2 skip if it's not available

[jreback]

thanks @TomAugspurger can fixup if needed later. let's open an issue to track this & revert when we can.
