  Debian GNU/Linux, guile-gtk and everything else installed from CVS in
/usr/local/gnome.  I already did the ld.so.conf thing; it works for all other
Gnome programs and has since last November/December.

  I checked, it's in there.

  Ok.

  No.  I cut that and pasted it directly into the message.

  However, after you mentioned LD_LIBRARY_PATH, it occured to me that I should
give that a shot (I had assumed that ld.so.conf was sufficient).  Lo and behold:

bluegreen:~/gaime> setenv LD_LIBRARY_PATH /usr/local/gnome/lib
bluegreen:~/gaime> guile
guile> (use-modules (gtk gtk))
(dlopening "libm.so" "/usr/lib/libm.so")
(dlopening "libm.so" "/usr/lib/libm.so")
(dlopening "libX11.so" "/usr/X11R6/lib/libX11.so")
(dlopening "libXext.so" "/usr/X11R6/lib/libXext.so")
(dlopening "libdl.so" "/usr/lib/libdl.so")
(dlopening "libglib.so" "/usr/local/gnome/lib/libglib.so")
(dlopening "libgmodule.so" "/usr/local/gnome/lib/libgmodule.so")
(dlopening "libgdk.so" "/usr/local/gnome/lib/libgdk.so")
(dlopening "libgtk.so" "/usr/local/gnome/lib/libgtk.so")
(dlopening "libguilegtk-1.3.so" "/usr/local/gnome/lib/libguilegtk-1.3.so.0")

  So..is it possible to do this using config files? (I don't like using
environment variables for config info unless it's absolutely necessary)

  For reference, ld.so.conf contains--
/usr/lib/tkstep
/usr/local/gnome/lib
/usr/X11R6/lib/Xaw3d
/usr/local/lib
/usr/lib/libc5-compat
/lib/libc5-compat
/usr/X11R6/lib
