cleaning house in osx

- use xslimmer or monolingual to strip down languages and unneeded architectures

- for all those compiling left overs of macports
sudo port clean --all -vf installed

- and mostly not needed inactive ports
sudo port -f uninstall inactive

- get rid of all the gui developer files (don't do this if you yourself develop applications on that machine, it will delete all designable.nib files)
sudo find / -iname "designable.nib" -exec rm "{}" \;
