If I understand the licenses correctly, the point about being GPL-compatible is
not putting everything on a CD. It's linking gpl code with non-gpl code. Say, I
create a command-based dump utility for PostgreSQL (and so links the pgsql
clientlibrary) but use the GNU Readline library for command-listory (which is
gpl'ed). If the PostgreSQL license wasn't compatible, I would bot be able to
link the Readline library into my executable.
