In each case, the issue was that the project wasn't declaring a dependency that it was using, and the fix was just to add the missing linkage.  Most of the cases involved gnome ports failing to link against gmodule-2.0, but there were a couple others.

Are the changes that have already been committed to trunk considered to be a complete solution? Can one upgrade to trunk and install and upgrade ports at will and expect everything to work (with the exception of bugs like the ones you're finding and fixing above)? I got the impression from some of the links that Joshua posted in the ticket that the order in which the flags were removed from packages was important, but the changes in base would seem to remove the flags from every port as it's installed.

You can't delete an .la file while it's still referenced by another .la
file. That's why trunk doesn't delete the files (by default), it deletes
the references. So yes, it should just work.
