Comment (by jpflori):
Indeed in ctypes/__init__.py
{{{
elif _sys.platform == "cygwin":
pythonapi = PyDLL("libpython%d.%d.dll" % _sys.version_info[:2])
}}}
Basically PyDLL, loads the library calling _dlopen which is an alias from
LoadLibrary from the _ctypes module (with an underscore).
And it seems it does not care about PATH.
But if I set LD_LIBRARY_PATH to point to where Sage's libpython2.7.dll is,
then its correctly loaded rather than the system one.
Not sure what happens on linux :)
I seem to remember some recent discussion about _ctypes which was not
built before and caused troubles recently.
