New submission from Philip Jenvey :
There's two different stub loader generators in the code base:
build_ext.write_stub and bdist_egg.write_stub
bdist_egg's stub loader always assumes the presence of a __loader__ value, which
causes a NameError in some cases. build_ext's version of the stub loader does
the right thing and only messes with __loader__ if it exists -- the following
patch applys that check to bdist_egg's stub loader
This fix is particularly important for packages with optional C extensions
deployed to Google App Engine (like simplejson, Genshi). Compiled extensions
won't be imported by GAE (as they're not supported), so instead the stub loader
is imported. Without a __loader__ present this results in:
File "/base/data/home/apps/sluggo-exp/2.1/lib/python2.5/site-
packages/simplejson-1.8.1-py2.5-macosx-10.3-i386.egg/simplejson/_speedups.py",
line 5, in __bootstrap__
del __bootstrap__, __loader__
NameError: global name '__loader__' is not defined
instead of an ImportError, which these packages expect to be raised when they
need to fallback to the alternative to the compiled extension
This should really make it in for the next release; prioritized as critical
