?  Can you provide a reference?  I thought the mainissue with
gnuplot's weird GPL-incomplate license is that only the original
authors are allowed to initiate distribution of modified versions of
the source; anybody else must distribute the unchanged sources +
patches.

Maybe we can include openssl in Sage as long as no GPL'd components of
Sage binary link with it... but that is a fine line.  Linking against
it as a system library is less of a fine line.
