Thank you for your reply. I used RPM. So the problem is "Standard" or
"No-standard" python.
What do you mean Standard or Non-standard?
As I said in my previous email, by "standard" I mean the Python included
with Fedora. This is /usr/bin/python. You said you had several other
versions of Python installed in /usr/local/. Fedora packages don't
install there, hence "non-standard". These packages won't work with
Modeller unless you set PYTHONPATH accordingly.
rpm -ql modeller | grep site-packages
will show you the directories where Modeller is installed for each
standard version of Python.
Note also that if your Python is 32-bit, you need the 32-bit version of
Modeller (ditto for 64-bit).
