Re: [Visualpython-users] Linux installation

[Bruce S. <bas...@nc...>]

It does seem to be using the desired version of Python, as the full
path created is

/usr/local/lib/python2.6/site-packages

which contains the intended python2.6. I also tried replacing $PYTHON
with python$PYTHON_VERSION and still got site-packages. It's really
hard to understand how sysconfig.get_python_lib can act differently
within the autoconfigure environment.
