Are others having problems building both llvm13 and llvm15?
I get errors when trying to rebuild llvm13-13.0.1_3 and upgrading llvm15-15.0.6 to llvm15-15.0.6_1 on 13.1-STABLE.

 What errors?  Do you have any out of swap errors in your logs?

No swap errors. Just rebuilt with "portmaster -d -m MAKE_JOBS_UNSAFE=yes llvm15" and got the following error:

Sphinx-err ends with: ModuleNotFoundError: No module named 'commonmark'

I only have py-39-recommonmark-0.5.0_2 installed, and portmaster doesn't build any other "commonmark" ports.

 Hmm. Do you have py39-CommonMark-0.9.1?  (Why is it CamelCase?  That is
confusing.)  I wonder if there's some messed up dependency tracking.  A
forced reinstall of py39-recommonmark-0.5.0_2 and dependencies might fix

What does your system/vm config look like?  The default configuration
builds FLANG which unfortunately requires quite a lot of ram.
Not building with FLANG support.

I guess that I'll try building it without DOC support.

 Hopefully that works.

I just rebuilt py39-recommonmark-0.5.0_2 and all its dependencies and get the same error. I rebuild with DOCS turned off and it successfully built.
I don't have py39-CommonMark installed, but it complains about a conflict with cmark that is installed. (I know that if I remove cmark, then it will then build correctly - and I assume llvm15 w/DOCS will also.)
