X, libxpm, and other stuff.

Hey folks,

I have decided to play with oroborus which is one of the rpms at
http://www.opendarwin.org/~mww/RPMS/i386/.

Unfortunately, it won't go. :]
I have rpm -i and it makes a few directories etc.
I changed my .xinitrc to exec oroborus and commented out AfterStep.
When I "startx" I get the default grey mesh background and a mouse cursor
and that's it.

According to Markus' dependencies I need to have XFree86 and Perl 5.8,
both of which I seem to have. I have read that I need libxpm also and
wonder if someone could tell me how I would tell if I have it.
I have tried find / -name libxpm but it doesn't seem to be there.
I also looked where my libpng and libjpg are and there is no libxmp.
I wonder if besides telling me where to look someone could point me in the
direction of an rpm for it or an rpm that will install it.

I am trying to get my head around X but find a lot of it confusing.
How come when I have installed XFree86
(org.opendarwin.X11-7.2.1-1.i386.rpm) I also have something called XDarwin
in one of my directories?
I thought XDarwin was a different implementation of X11.

Best Wishes,
David Walker
