port provides and symlink'd $prefix

[Daniel J. Luke]

So, I've got a host where I have a nonstandard $prefix, but have an /opt/local symlink to it so that I can still get binarys from the buildbots.

macports.conf prefix is /opt/local while portdbpath points to the 'real' path. Things work well except that `port provides` fails.

It looks like this falls apart when port does a [file normalize $filename] (in proc action_provides). I'm not sure there's a generic solution to this, but maybe it would be good to not try to normalize $filename if it's an absolute path? That way `port provides /opt/local/bin/foo` would still work for me?

Thoughts?
