I do have zlib installed via MacPorts. A bit rusty on how to make this visible. Also, can it be detected automatically?

[jasperblues]

For Macports:

set -xg LDFLAGS '-L /opt/local/lib'
set -xg CPPFLAGS '-I /opt/local/include'
set -xg PKG_CONFIG /opt/local/lib/pkgconfig

^-- or the bash shell equivalent

Hi! asdf-python is simply a wrapper around python-build so the issue should most likely be open there. I am happy to add something to the README if it helps though. I will close for now, please comment if you think this should be re-opened. Thanks!

@danhper It don't use Python so often, so had to google around. I guess the issue (with building) will already be familiar to regular Python users.

This ticket should be index now, will appear in search results for others who need guidance.
