What you're doing should be ok I think, you could really pick any 
binary/library installed by the dependent-on port and even lib versions, e.g. 
somelib.5, are only needed if versions matter AFAIK. If you just installed 
mysqltcl did you perhaps just not run rehash?

Obviously if you require a package and you know you need lib XYZ from it you'd 
add a dep specifically for that, but usually I think all you need is to point 
to something (a binary in PATH or a known library) that is uniquely installed 
by the port that provides what you need. Perhaps someone can correct me if 
this is not so.

If it may turn out to be the issue here: IMO you should not (need to) include 
a path in these cases, e.g. ${LOCALBASE}/bin. It should (almost) never be 
needed if PATH and lib paths are updated. Something's odd or wrong if it's 
needed.

(Please note: I don't use this particular port)

Then again, it might be tea leaves also... The Docs are of course 
in /usr/ports/Mk/bsd.port.mk. They're still in beta though :)

HTH,
