I've started doing some trial rebuilds on a system with the test python3 
packages installed.  I'm finding that cygport doesn't pick up any python 
dependency for some packages (such as texlive-collection-binextra-doc) even 
though there's a script with a shebang "#!/usr/bin/env python".  Marco, you've 
probably said this already, but could you confirm that this is to be expected 
until cygport is modified?
