It seems to me a BSD (old fashion)-like:
"Permission to use, copy, modify, and distribute this software and its =

associated documentation for any purpose and without fee is hereby =

granted, provided that the above copyright notice appears in all copies, =

and that both that copyright notice and this permission notice appear in =

supporting documentation, and that the name of Secret Labs AB or the =

author not be used in advertising or publicity pertaining to =

distribution of the software without specific, written prior permission."

Quite hazy. If you distribute or derive your code from that software, =

this should be GPL-incompatible: the requirements after "and that the =

name..." are restrictive for the GPL.
However linking should be different, since all the GPL-incompatible =

requirements of the PIL licence apply only to redistribution, not use or =

linking, so GPL should be safe.
I'd stick with GPL and mail to the GNU guys for advice, if you're really =

concerned.
