Comment (by barracuda156):

 Replying to [comment:2 ballapete]:
 > I have a similar failure mith modules for `Python 3.11` on PPC Leopard,
 Mac OS X 10.5.8. For example see attached main.log.

 Could you summarize what exactly fails? I would like to try reproducing.
 (I do not have a fully working Leopard setup atm, but I have 10.4 and
 10.6, which supposedly gonna share these issues.)
 I am pretty sure basic `python311` ports install fine, though I did not
 conduct any specific testing, and select ports are and were always broken
 for 10.5 (and 10.6 ppc), even though they could be building with no
 errors.

 On a general note, I have an impression that:

 a) compiler choice is broken now with ''some'' Python ports, and Xcode
 gcc/clang can be picked when modern gcc is required;
 b) meson-python has broken arch detection for PowerPC (this is not a guess
 really, but rather a fact), but it matters in some specific cases.

 (Also recently a number of Python ports were broken by introduction of
 Rust dependency; hopefully will be fixed soon. But this does not seem to
 be relevant here.)
