make sure you have
libxml
oaf
ORBit
gnome-libs
gnome-vfs
gconf
libglade
scrollkeeper

mozilla-1.7 (or other)

configure with:
--prefix=/usr --with-mozilla-libs=/usr/lib/mozilla-1.7 --with-mozilla-includes=/usr/include/mozilla-1.7 --with-mozilla-snapshot=1.7

--be sure to match the above with the version you have installed
-- gconf config dir is /usr/etc/gconf
-- scrollkeeper is probably not needed at runtime
-- gconf may not be needed, but enables you to do set
   extra configurations which are unavailable otherwise.
-- strange that slib wasn't required -galeon installs slib schema files
