Hard-coded paths?  Hum.  Sorry for the confusion: although PyPy's own
sys.path includes this 'pypy/lib' directory, importing '_codecs' doesn't
find the file pypy/lib/_codecs.py because it is special-cased in
pypy/module/sys2/state.py.  Holger just removed it from there, so now
you should be able to just import _codecs normally.

In general, importing the pypy package at app-level is likely to make
things crash.  A few days ago I moved a similar piece of code out of the
way because it confused the translation process.  Mea culpa; I should
have signalled the problem and proposed a solution.  (On the other hand,
feel free to ask on pypy-dev when you get such issues :-)


A bientot,

Armin.
