[Savage40] "No package 'libdrm' found"

[Rácz János]

Hi!

I am a common (and old) user of the manual 
"http://dri.freedesktop.org/wiki/Building"
for my laptop (savage driver).

I had to remake that method because of a kernel changing.
When I am on
"1.6. Building Mesa 3D Drivers on Linux"
(after typing "make linux-dri" or "make linux-dri-x86")
I got an error message (the problematic part of the text):

"Package libdrm was not found in the pkg-config search path.
Perhaps you should add the directory containing `libdrm.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libdrm' found

Of course I tried to modify some config file, but It was not managed to solve 
the problem. It is sad, because it (following instructions in 
"http://dri.freedesktop.org/wiki/Building") was a simple and harmless method 
installing 3D on my laptop.

I would be very grateful if you could help me installing dri driver.
Thank you!
