Hi, I'm experimenting with using non-default library directories by tweeking pypy.tool.lib_pypy however I came up with the following error when translating with pypy:
[translation:ERROR] Error:
[translation:ERROR] Traceback (most recent call last):

__file__=autopath_py))
[translation:ERROR] IOError: [Errno 2] No such file or directory:
'/usr/local/pypy-1.9/pypy/tool/autopath.py'
This error does not happen when translating with python.
Upon investigation I found that pypy has:
# pypy -c 'import sys; import pypy.tool.lib_pypy; print "ctypes_config_cache"
in sys.modules.keys()'
True
but python has:
# python -c 'import sys; import pypy.tool.lib_pypy; print "ctypes_config_cache"
in sys.modules.keys()'
False
also:
# pypy -c 'import sys; import pypy.tool.lib_pypy; print
sys.modules["ctypes_config_cache"]'
<module 'ctypes_config_cache' from
'/usr/local/pypy-1.9/lib_pypy/ctypes_config_cache/__init__.pyc'>
note the above always happens regardless of pypy.tool.lib_pypy being modified
or not.
It appears to me that there are two bugs:
1) pypy ends up importing ctypes_config_cache when it shouldn't???
2) py/_path/local.py doesn't ensure import from correct location
And attached is a patch for fixing (2), which works around (1).
Regards
