Hello,

Looking at the Aria code it looks like it wants an environment variable 
calld CCPNMR_TOP_DIR set up in the environment.  But I can't see that it 
actually uses this variable.  And so when it comes to importing the CCPN 
libraries I think it is just using the globally set PYTHONPATH.

Now in (at least early versions of) v1 of Analysis these variables were 
generally set globally.  But in v2 they are set in the bin/ scripts so 
never are set globally.  So my first guess is that your global PYTHONPATH 
(e.g. as set in your .cshrc file) points to v1 instead of v2.
