xmgrace installation failed, problem of X11-devel
 

Hi

I am on a Red Hat Enterprise Linux Client release 5.5 for 64-bit x86_64 and I try to install xmgrace.
During the ./configure command, I have this message :
checking for X... no

After research, this message is due to the fact I have not installed libX11-devel. So, I try with yum but no libX11-devel...

However I find it on the rhn (libX11-devel-1.0.3-9.el5.x86_64.rpm). I download and install it. Now I have problems of dependencies, I need :
- libX11 = 1.0.3-9.el5
- libXdmcp-devel
- xorg-x11-proto-devel >= 7.1-2

xorg-x11-proto-devel can't be found with yum, I download it by the rhn and install it and again, problems of dependencies, I need mesa-libGL-devel.

mesa-libGL-devel is not available by yum. I download it by rhn and install it and a new problem of dependecies, I need libX11-devel!!

So I'm disappointed, for install libX11-devel, I have to settle the dependencies which need libX11-devel...

My questions are :
- Is it normal that the devel packages mentionned above can't be found with yum?
- How I can install libX11-devel?


Thanks
