Depends if you do have those packages installed. Numeric is from
dev-python/numeric, for example.

Also, be careful when you parse the output of the command. Most of the
.pyc and .pyo files in the python2.5 directories are byte-compiled
version that python generated dynamically the first time they are
used. For example: ..../Numeric/numeric_version.py was installed by
the ebuild and thuse qfile tells me it belongs to dev-python/numeric,
but .../Numeric/numeric_version.pyc is listed as an "orphan". While it
is safe to delete, it will just be regenerated again later, wasting
computing cycles. 

Ditto for some of the files in the perl directory.
