Tarballs carry timestamp information. So those timestamps are whatever the
timestamps were for the person who made the tarball when he made it.

The files, but not the common directories. For example, if you are also deleting
the gcc that you got from hpc.sf.net (recommended!), you can just delete
/usr/local/lib/gcc/ entirely, but you shouldn't delete /usr/local/lib/.

If you are using Python 2.4, there will be numpy/ and scipy/ directories in the
following directory. Delete them.
