Ports has a predefined method of doing this: USE_GNOME= gtk20 libxml2

Most programs I've seen are PREFIX safe. It is almost always better to use
$PREFIX. The only exception I've ever seen is something like perl which many
broken programs use.

There is a feature "@dirrmtry" which will only remove the directory if no
one is using it
