nope. i misunderstood "loading on Linux the FTGL lib". sorry.

i'm doing something similar but with cmucl, i wanna use my favorite
media library from lisp, but it has ugly API so i'm writing some
helper functions to hide ugliness from lisp. i can use the library
from C without much thinking, but when loading it into lisp i have to
say:

(load-foreign
  '("artm-wrap.o"
    "libmedia1.a"
    "libmedia2.a")
  :libraries '("-lc"
	      "-L/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.2/"
	      "-lgcc"
	      "-lz"))

i guess the libmedia uses some gcc-specific features on linux which
require linking with gcc... i'm not sure how this would have looked
in allegrocl, but the issue might be the same, no?
