Yes, that would be best. Perhaps along the lines of:

;;;; bb.setup -*- Scheme -*-

(define has-flu? (zero? (system "flu-config --version")))

(make/proc
 (list (list "bb-support.so" '("bb-support.cpp" "bb.h")
             (lambda ()
               (run (g++ -Os -fomit-frame-pointer -fPIC -c
                         ,(if has-flu? "`flu-config --cflags` -DBB_USE_FLU" "")
                         "`fltk-config --cflags`" bb-support.cpp)) ) ) )
 "bb-support.so")

(run (csc bb.scm -s -O2 -d0
          -L "\"bb-support.o `fltk-config --use-images --use-gl --ldflags 
--libs`\""
          ,(if has-flu? "-L \"`flu-config --ldflags --libs`" "")
          -ld g++) )

(install-extension 'bb '("bb.so"))

Thanks for the good work! I'll update the website (and in the meanwhile
play a little with BB... :-)
