 Ryan,
 I think it's ok for you to do the modifications you think are necessary.
 The whitespace differences must come from my using emacs and its tcl mode,
 that I'm very fond of. You could put yourself as a maintainer there also!

 I don't think it would be a good idea to make any port depend on any
 -devel port. In this case, MySQL is approaching a 5.1 release proper, but
 there may be some changes still. I expect 5.0 and 5.1 releases to be
 binary compatible, which is why I think 5.0.* ports won't be maintained
 after 5.1 release. This is not the case with PostgreSQL the
 incompatibility being the reason for ports 8.0, 8.1, &c.

 BTW, Linux -devel packages are for entirely different purpose, they are
 meant to include files for development with the packages, e.g. header
 files.
