Yeah, xinitrc is the place for this.  Be sure to hard-code the *result* 
of running that pkg-config command, not the command itself... no need to 
shell out again, and I don't want to assume pkg-config is available at 
runtime (tho in practice it should be).

Also should do something like this instead:

if test "x$LIBGLADE_MODULE_PATH" = "x"; then

I also wonder if we should test to make sure that $xfce_libglade_path != 
$default_libglade_path, and if not, then don't set the env var.  But I 
guess it doesn't matter.

We should also do this for GLADE_MODULE_PATH -- less critical since it's 
only for developers, but it doesn't hurt to be complete.

Actually, if we do all this, then we might want to consider defaulting 
the libglade/glade modules paths to $libdir rather than libglade/glade's 
$libdir.  But in that case I'd want to move this env var setting to 
startxfce4, since people with custom xinitrc files will miss this change 
and have broken dialogs.

Actually^2, I think at some point I'd like to change how our xinitrc 
stuff works so this is a moot point.  The systemwide xinitrc that we 
install should *always* get run, and should source a per-user xinitrc if 
one exists.  That way global changes like this won't get lost if the 
user has an old, customised xinitrc in their homedir.  But that's for 
4.8.  For 4.6 we should just fix the libglade/glade issue as you've
