py311-numpy uses -march=native on PPC, which breaks the build

[kencu (Ken)]

is this on a 10.6 system running rosetta, or on 10.6-for-PPC?

Replying to kencu:

is this on a 10.6 system running rosetta, or on 10.6-for-PPC?

Rosetta. I do not open tickets specifically for 10.6 PPC (if a failure is not also confirmed on 10.5 and/or Rosetta), and whenever I refer to it for w/e, that is done explicitly.

[barracuda156]

However, while the failure may be specific to Rosetta, PPC support in non-existent there. I will see if I can fix that – at that Altivec is used, for instance.

Edited: Sorry, ignore this, outdated portfile. Will try again now.

UPD. Yeah, it still fails with -march= flag.

Should actually be not too hard to fix. If arch detection is made sane, it will likely fix the build.
