I haven't been able to build a fresh clone of GSLL for a while now (maybe never?). This has already floated up on this list before, but GSLL/CFFI-GROVEL don't know where to find header files. There seems to be no way to tell them other than changing the source and passing a special :cc-flags on the groveler line. I also have to do this with FSBV. It would be nice if there was something in CFFI-GROVEL that allows you to say "check here, here, and here for my header files." I'm talking about something like CFFI:*FOREIGN-LIBRARY-DIRECTORIES*. I am bringing it up here first since I might be mistaken about the state of things. Any other people out there have headers in places CFFI-GROVEL doesn't think to look? Do you have a better solution?
