/opt/local/var/macports/distfiles/ contains the distfiles of what you
installed. The dates of creation should inform you.

Unfortunately, new installs are not what you want to get rid of as you
reinstalled things that were already there! (however, the distfile date
should not have changed)

Why don't you want to use force? If you did not use force to install,
then removing a port will not damage another one. However, there exist
scripts that give you a tree of dependencies (search the archives of the
lis), you could use them to get rid of new ports with no dependencies
(recursively).

You may want to "port clean --all" those ports to get rid of the
ditsfiles (source tarballs) and the packages (archives of what was
installed, you may not have this enabled).

Good luck,

Emmanuel
