Whenever I ask pyenv to install something, I get some issues that seem to be related to compiling. From the build output:

I’ve installed and used pyenv for years, but I set up this computer in a hurry, and I can’t figure out what’s wrong.

Things I’ve thought of:

• I deleted and reinstalled homebrew
• I used homebrew to install all build dependencies
• I installed pyenv through a git checkout
• I deleted and re-installed Xcode command line tools
• brew doctor is happy

What am I missing?
