Created attachment 337722 [details, diff]
Patch for the ebuild

Disable the use of target CFLAGS for make as well, not just configure.

I suspect your patch is backwards. :-)

[Comment 3 Andrei Slavoiu 2013-02-04 16:43:19 UTC]

Indeed, I got the arguments to diff reversed. Use patch -R to apply it.

(In reply to comment #1)

why is this necessary ?  does the Makefile pull $(CFLAGS) from the env in addition to the value it was configured with ?  this is not typically how makefiles produced by autoconf should operate.

[Comment 5 Mike Gilbert 2016-10-10 20:08:46 UTC]

This has likely been resolved by not building/running pgen when cross-compiling in newer python versions.
