[Mesa-dev] [mesa-demos-git] make fails on eglkms

[Lone_Wolf]

I am trying to build mesa-demos git master version 20120112 on archlinux.

  ./autogen.sh --prefix=/usr
  make

last lines of output :
eglkms-eglkms.o: In function `main':
eglkms.c:(.text.startup+0x40): undefined reference to `gbm_create_device'

the mesa i am running is also a git version , has gbm enabled, and gbm.h
is present in /usr/include .
(see https://aur.archlinux.org/packages/me/mesa-r600g-git/PKGBUILD for
details).
