I haven't looked at what would be necessary to fix UNIQUENAME collisions
in any great detail, but I think a number are due to setting PORTNAME to
something basically incorrect.

Hmmm... so there just has to be pkg.txz at some predictable URL(s) on
the FBSD mirrors? That doesn't sound like enough to justify keeping
LATEST_LINK related bits in the ports tree.

I think I see. You're thinking of packages that install the same files,
but maybe in a different location (eg. SITE_PERL) or that register
run-time dependencies on a number of different possible providers.
Couldn't that boil down to having several alternate .MANIFEST files in
the pkg? Plus some sort of final-location-independent way of naming the
files to be installed by the package?
On the matter of having alternate RUN_DEPENDS to be set at install time?
I've wanted to do something like that with databases/phpmyadmin for
ages. Most of the optional dependencies there are autodetected by the
PHP code at run-time, so it should be possible to just ask the user
which of them they want to have during pkg installation.
Cheers,
