Macvim and Pyclewn

[vito]

Has anyone been able to get pyclewn to work successfully with Macvim?

I was able to successfully install pyclewn (I believe). But whenever I run :Pyclewn from macvim I get:
The 'Pyclewn' command has been aborted.
Error: 'pyclewn' cannot be found or is not an executable.

I also tried:
:Cfile foobar
and
:Cecho
both of which are returning not an editor command

Thanks
