A list of the standard packages used by me are kept in ~toor/$HOSTNAME/packages/pkg_build, which when run will attempt to build those packages.
To get a list of the currently installed pacakges and there location run ~toor/$HOSTNAME/packages/pkg_list. This also gives possibly related packages of different versions but there is no guarrantee that it will find them all (i.e. look yourself to see the new packages).
