That presumes all additional files are installed via the ports mechanism,
or at least know about it, which is highly unlikely.  With plugins of
various types and machine-independent binaries like java .class files 
abounding, requiring every add-on to be installed by the ports mechanism 
isn't likely to work in the long run.

I can see how a program installed by the ports mechanism should use the
mechanism you're advocating, but I don't think it applies to all cases.

In this case, it was a mysql driver, obtained as a binary (.jar of 
java .class files).  But things like gimp plugins have the same issue.
