* If you make no special configuration, the help is installed in
  /usr/local/share/gnome/help. Unfortunatelly, without gnome as window manager,
  the help file must be only in /usr/share/gnome/help.

* If you have small buttons without text or icon inside, this means glade fails
  to load icons. Glade seems to search icons only in /usr/share/pixmaps but the
  configuration script put them (by default) into /usr/local/share/pixmaps.

For these 2 problems, here is the possible solutions:
1) use the rpm file instead of the tarball.
2) instead of "configure", do "configure --prefix=/usr" to force the script to
   install program and data into /usr instead of /usr/local. In fact, that's 
   what the rpm does.
3) the quick and dirty way: 
   ln -s /usr/local/share/gnome/help/dc_gui /usr/share/gnome/help/dc_gui
   ln -s /usr/local/share/pixmaps/dc_gui /usr/share/pixmaps/dc_gui
