[Dominik Reichardt]

Why don't you just symlink it? No pain this way, everything *thinks* it is on /opt/local while it is actually on the other drive...

The only thing is, macports defaults to storing db data (for example, MySQL and PostGres) under /opt/local/var, and I didn't want that data on the SSD. I guess, I could still have macports on the SSD and have the db data on the external drive, and just tell the db software to use the different directory.
