Ok... I was looking at it from the standpoint of someone who wants the 
newest version and doesn't care of the pkg-plist is stale.  They could 
just bump PORTREVISION and reinstall.

So... how about this:
- A distfile target which generates a distfile.  The idea being that 
this would be the one on the local distfile mirror or what have you.
- A WITH_SVN option (defaults to off) which allows the end user to 
specify he/she wants to use the subversion.

In this case then, the end user would need to bump PORTREVISION and 
enable the WITH_SVN option.
