[plt-scheme] OpenGL Bindings

Hi all,

I'm trying to compile OpenGL Bindings by Scott Owens using
PLTScheme v200. I'd like to know if can anybody explain me why am
I getting the following error...
Everything compiles ok inside gl-vectors but in the root dir of sgl:
bash-2.05$ sh ./makefile.ss
make: checking compiled/native/i386-linux
make: making compiled/native/i386-linux because compiled/native/i386-linux does not exist
make: made compiled/native/i386-linux
make: checking all
make:  checking compiled/native/i386-linux/gl11-prim.so
make:   checking gl11-prim.c
make:    checking gl11-prim.ss
make:     checking gl11.h
make:     checking c-decl.ss
make:    making gl11-prim.ss because gl11-prim.ss does not exist
make: Failed to make gl11-prim.ss; reference to undefined identifier: make-lex-buf

Any ideas?

Best regards,
