Hi Marco,
Yes it should work. If you start pyclewn from the command line
and not from Vim, running the following command should also work in a
virtualenv:
python pyclewn ....
The "#!/usr/local/bin/python3" line is actually edited in the script
by distutils itself when building the pyclewn package, see:
http://docs.python.org/distutils/setupscript.html#installing-scripts
This offers a certain level of protection (for example a python3
pyclewn implementation will run with a python3 interpreter, and not a
python2 one) which is useful when pyclewn is started from within Vim
where debugging startup errors is not easy.

When pyclewn has been installed using a local installation, there is
no need to change sys.path as it is already updated in the pyclewn
script.
