Well, I think I am missing something here. when I said *almost*, I
meant *almost* (execpt some gtk only based packages). All the gnome
packages install their pixmaps at $(datadir)/pixmaps/$(package) dir.
Obviously, $(datadir)/pixmaps dir is the standard dir for gnome
to put gnome pixmaps. Here the $(datadir) is the datadir confi-
gured by the gnome and not by the application.
So, as long as the gnome datadir and the app datadir are
same, there is no problem, but when they are not same, most
(almost all) programs cannot find the pixmaps.
I did an experiment yesterday. I did three types of installations
for a gnome application.
1) prefix=/usr (root)
2) prefix=/usr/local (root)
3) prefix=/home/naba/local (user)
Only in case of the first installation did the application
found the pixmaps and help topics (for the help menu).
And *that* installation statisfy the condition that
gnome_datadir == application_datadir.
The applications that installed pixmaps in the gnome
pixmap dirs and help files in gnome_datadir includes many
standard gnome packages such as gnumeric, gmc, eog, gedit,
etc etc. And I am pretty sure about *almost* all gnome
packages.
I am wondering haven't the maintainers of these packages
got this complaint about local installation?
Only a very few gnome packages like Abiword (which I have a hunch
that it is a gtk app and not gnome app) maintained their
own pixmaps in their datadir.
Probably they were smart and they knew this problem would
arrive in future (so they opted for do-everything-yourself
philoshophy :-)).
If an application is forced to manage its own
pixmaps and help files, then that would very much
defy the philosophy of the 'Best desktop environment'.

Is there any other API calls with gnome that take cares of
these problems without letting the author handle his/her own
pixs and helps in project's datadir?
I have the assumption that only gtk (not gnome) packages
manages their own pixmaps and help.
I honestly beleive that we need to do something to allow
local installaions of gnome packages just like gtk and
other non-gnome packages.
I've no idea if these problems have been addressed, but
I really feel stupid when I can't do local installation
of gnome-packages while others could be very easily done.

BTW, Miguel, you and your frens really did a very nice job witb Bonobo.
Keep the good work up. Someday I would also like to help with the
development of Bonobo, may be just with the documentation or something
that you ppl don't find time for.
