To pass to genlop with --date, in order to get a list of all packages
installed after that date.

Of course. The question was about finding all packages installed after a
particular reference package, in this case gcc. If the reference package
is no longer installed 9impossible with gcc of course) the question
becomes pointless.

It would, you'd only have to modify it to use genlop's -u option.

All of this is irrelevant anyway, using genlop and parsing the output is
going round three sides of a square instead of going in a straight line
with find. Using a non-standard bash or perl script to parse the output
of an optional perl script seems rather redundant when you can do it all
with one call to a core command.
