Failure on garnome 0.26.2 on RH9

[Joseph Phillips <jphillips amphus com>]

Trying to compile the latest garnome 0.26.2 on my RH9 system.  Got the
following error:


configure: error: *** libX11 not found. Check 'config.log' for more details.
make[2]: *** [configure-work/main.d/gtk+-2.2.4/configure] Error 1
make[2]: Leaving directory `/opt/garnome-0.26.2/gnome/gtk+'
make[1]: *** [../../gnome/gtk+/cookies/main.d/install] Error 2
make[1]: Leaving directory `/opt/garnome-0.26.2/gnome/metacity'
make: *** [../../gnome/metacity/cookies/main.d/install] Error 2


Does anyone know what is the problem?  What is libX11 and why can't it find
it?  Thanks.
