I understand your concerns regarding setting of PYTHONPATH while
multiple versions of Python are installed on the same machine. My fix
however does not use PYTHONPATH. The GNUTLS wrapper module for PYTHON
loads the GNUTLS dll's and it was not able to find them. Using FileMon
(win tool) I found out the paths that are scanned and I copied the
dlls to one of such paths. I still do not like this fix. This is a
Can you explain maybe with some sample how to set .pth files? Maybe
this will resolve my issue.
