This really looks like a python issue when complied on the Mac prefix environment. Python 2.6.5 (release26-maint, Nov 22 2010, 14:20:01) [GCC 4.2.1 (Gentoo 4.2.1_p5664, Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import locale >>> import codecs >>> codecs.lookup(locale.getpreferredencoding()) <codecs.CodecInfo object for encoding mac-roman at 0x4225e0> >>> codecs.lookup('x-mac-simp-chinese') Traceback (most recent call last): File "<stdin>", line 1, in <module> LookupError: unknown encoding: x-mac-simp-chinese
Older python ebuilds used to remove the /usr/lib/python2.6/encodings/ directory when USE=build was enabled. You might check whether that directory exists and contains a healthy set of encodings.
The docs say locale.getpreferredencoding() "only returns a guess": http://docs.python.org/library/locale.html#locale.getpreferredencoding So, maybe it's valid for the returned encoding to trigger a LookupError? If so, it would make sense for the caller to check for this case and fall back to a reliable encoding like utf_8 or ascii if necessary.
This commit should fix the issue with equery. http://git.overlays.gentoo.org/gitweb/?p=proj/gentoolkit.git;a=commit;h=2b5cf6a3b096ab728212a210075bd1f4d173dac0
This was released in gentoolkit-0.3.0
