There were discussions on comp.lang.lisp several times about the
appropriateness of GPL and even LGPL for Lisp programs.  I think the
general feeling is shown well in

http://groups.google.com/address@hidden

Franz Inc. even thought they had to modify the LGPL, see

http://opensource.franz.com/preamble.html

I think it would be reasonable if the FSF would clarify its position in
this matter.

At the moment I prefer the BSD licenses because I also think that it is too
difficult to integrate GPL code with software under different licenses in
the tight coupling of a Lisp environment.  In addition to Franz Inc.'s
concerns, there is one more point which I find critical with the LGPL, and
this is that it allows the user to update to the GPL.  That is, there might
be a free software zealot who takes an LGPL'd library, improves the code
somewhat and starts a concurrence project under GPL.  This might be
disastrous to the LGPL'd form of the library.  (I want to add that I cannot
estimate how realistic this scenario is.)

I assume you would need some exception clause to the GPL?  (As in the Bison
case.)
