I tried the exact same steps. This time, the whole thing went through
fine, but when I do (test-gtk::gtk-demo) it complains about
libcellsgtk.so.

(test-gtk::gtk-demo)

debugger invoked on a CFFI:LOAD-FOREIGN-LIBRARY-ERROR in thread
#<THREAD "initial thread" {10022BFC31}>:
  Unable to load foreign library: libcellsgtk.so

Here's the error message:

Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
  0: [RETRY    ] Try loading the foreign library again.
  1: [USE-VALUE] Use another library instead.
  2: [ABORT    ] Exit debugger, returning to top level.

(CFFI::HANDLE-LOAD-FOREIGN-LIBRARY-ERROR
 "libcellsgtk.so"
 "Unable to load foreign library: ~A"
 "libcellsgtk.so")

I build libcellsgtk.so in root/gtk-ffi/ and placed it in /usr/lib, but
sbcl couldn't find it.

Even though cells-gtk loaded fine in sbcl, when I do a (use-package
"FFI"), it still can't find FFI. (find-package "FFI") returns NIL.

Thanks,
Vinay
