Steffen, thanks for coming up with this patch. Did you talk to upstream? It would be nice if we can ascertain that a similar patch will be in the next upstream release.
Comment 7 Tolga Dalman 2010-11-29 14:07:08 UTC
Same issue here with Python 2.7.1.
Comment 9 Francesco Riosa 2010-11-29 21:57:15 UTC
Simple fix COMPILE IT WITH USE=-python !

That's probably not right, plus the Python 3 code is incomplete and
its Python extension is badly designed. I know, because I created
it. :)

What probably happened is that they removed the #define for
PyBytes_Decode that was in 2.6, because there those defines were to
ease transition to Python 3 (wherein "PyString" stuff is renamed
"PyBytes"), but Python 3 wasn't actually going to have a
PyBytes_Decode -- the function was simply going to be dropped.

Simplest fix in that case is to go back to the old name:

Comment 10 Hanno Böck gentoo-dev 2010-11-30 23:15:30 UTC
Added patch from upstream. All further discussion about better solutions should be handled with upstream.
