[ab] Ubuntu Edgy + lispbuilder sdl and sdl-gfx

[Anthony Fairchild]

Just an FYI, with some slight modifications to the code I was able to
get the sdl and sdl-gfx examples to run under Ubuntu Edgy.  The
sdl-image stuff worked without any changes.  I did not try any of the
other sdl-* projects.

Ubuntu Edgy installs these versions of the libraries:

anthony at aft41:~$ locate libSDL
/usr/lib/libSDL_mixer-1.2.so.0.2.4
/usr/lib/libSDL-1.2.so.0
/usr/lib/libSDL-1.2.so.0.7.3
/usr/lib/libSDL_gfx.so.4
/usr/lib/libSDL_mixer-1.2.so.0
/usr/lib/libSDL_image-1.2.so.0.1.4
/usr/lib/libSDL_image-1.2.so.0
/usr/lib/libSDL_net-1.2.so.0.0.5
/usr/lib/libSDL_net-1.2.so.0
/usr/lib/libSDL_gfx.so.4.9.0
/usr/lib/libSDL_console.so.1.3
/usr/lib/libSDL_console.so.1
/usr/lib/libSDL_ttf-2.0.so.0.6.2
/usr/lib/libSDL_ttf-2.0.so.0


So I modified the library.lisp files in both sdl and sdl-gfx projects,
adding  "libSDL-1.2.so.0" "libSDL_gfx.so.4" to the
CFFI:DEFINE-FOREIGN-LIBRARY calls.

With those changes everything works great.
