When I try to build pandas again, I get the following error.

AFAIK, we shouldn't need to build Pandas on Gitpod, it builds automatically. And on top of that the issues are raising because Gitpod doesn't allow tinkering with the env. Overall the Gitpod development env is broken :/

[theuerc]

The build instructions for gitpod are essentially an automated version of the dockerfile installation flow on https://pandas.pydata.org/docs/development/contributing_environment.html

The issue is that the installation instructions have changed recently. It's just a one-liner fix, so I'll submit a pull request right now.
