Probably no more or less than, say, any program on your system is a
derived work of glibc.  (I'm assuming here that cups-pt links against
libcups to do its magic.)  Note also that clause about not being
required to carry the exceptions forward; that likely means that linking
to libcups is fine as long as libcups doesn't use either of the two

I would strongly recommend, however, that someone get a license
exemption from upstream cups-pt for OpenSSL.  I'm planning at some point
to turn on SSL support in the cupsys packages.  I've already tried once,
but ran into similar problems with gs-esp (which I may be able to work

I'm also seriously considering trying out the OpenSSL compatibility in
recent gnutls.  The problems with license compatibility in libcupsys are
enough to drive me batty.
