Comment(by macports@…):

 Hey, if we are going to make upgrade intelligent, maybe we should make it
 really smart and have it build libraries BEFORE the things that depend on
 them rather than AFTER. That way, when something happens like OpenSSL is
 updated, a port upgrade would build it first rather than last. That'd save
 the time of the devs who are busy bumping revs on everything to clean that
 mess, AND it would save the time of the users for who the upgrade built
 OpenSSL AFTER all the ports with bumped revs who now have to upgrade
 --force a whole pile of basic stuff. Cause, you know it sucks when that
 port upgrade fails because it upgraded OpenSSL AFTER subversion and then
 hits a port that wants to use the now-broken subversion to fetch the files
 to build the current port being upgraded.

 Also, when we are in this situation, it'd be nice if macports had a
 function to check the version of libs linked against my installed ports
 and rebuild as necessary to resolve those with missing versions. That
 would be much better than posted a script to the mailing list that is
 written for one specific library and version in question and has an
 assumed prefix hardcoded. I know a generic and reusable solution is really
 pushing it but in the long run it's a win.
