I have done some progress.  I realized that I didn't have
libcellsgtk.so properly compiled and installed.  After doing that, the
global table includes the library:

* sys::*global-table*

((#.(SYSTEM:INT-SAP #x08074280) . "/usr/lib/libcellsgtk.so")
 (#.(SYSTEM:INT-SAP #x08073B60) . "/usr/lib/libgtk-x11-2.0.so")
 (#.(SYSTEM:INT-SAP #x08070300) . "/usr/lib/libgdk-x11-2.0.so")
 (#.(SYSTEM:INT-SAP #x0806FBC8) . "/usr/lib/libgthread-2.0.so")
 (#.(SYSTEM:INT-SAP #x0806F7B0) . "/usr/lib/libglib-2.0.so")
 (#.(SYSTEM:INT-SAP #x0806F570) . "/usr/lib/libgobject-2.0.so")
 (#.(SYSTEM:INT-SAP #x40014F90)))

This time, when I start the saved image, I get this different error:

paolo at plato:~/src/cells-gtk-2005-05-29$ cmucl -core cells-gtk-demo.core


Error in function RELOAD-GLOBAL-TABLE:
   Couldn't open library "/usr/lib/libcellsgtk.so": NIL
   [Condition of type SIMPLE-ERROR]

Restarts:
  0: [ABORT] Skip remaining initializations.

Debug  (type H for help)

(RELOAD-GLOBAL-TABLE)
Source:

It looks like sys::dlopen in reload-global-table fails:

When I do `make' in root/gtk-ffi, I get these messages:

paolo at plato:~/src/cells-gtk-2005-05-29/root/gtk-ffi$ make

Is this related?
