  help: `gssapi` (v1.11.1) was included because `htgettoken` (v2.2) depends on `gssapi`

while installing in a python 3.11 environment on the same machine works without issue:

I realize the build is potentially failing because I don't have gcc12 installed, but on my OS (Arch based CachyOS), having to install gcc12 via AUR is a bit of a lengthy process (with some issues, apparently). Would upgrading to support a newer version of the gssapi package potentially solve the issue here?

I don't have much experience with htgettoken in the pip environment. @duncanmmacleod can you advise?

[DrDaveD]

@duncanmmacleod Please reply

[duncanmmacleod]

I'm sorry for the delay, I could have sworn I posted a reply shortly after the ticket was originally posted...

I can't reproduce the problem using the cachyos/cachyos docker container, I presume you are running an older version of the OS.

If you can you reproduce the failure simply with {uv} pip install gssapi I encourage you to post an issue on the upstream pythongssapi/python-gssapi repo.
