Ahh ok then,

When i try and compile the current source from the repo
git://anongit.freedesktop.org/xorg/app/xrandr i get some errors at
compile time:

xrandr.o: In function `main':
.../xrandr.c:2969: undefined reference to `XRRSetProviderOffloadSink'
.../xrandr.c:2965: undefined reference to `XRRSetProviderOutputSource'
.../xrandr.c:3392: undefined reference to `XRRGetProviderResources'
.../xrandr.c:3397: undefined reference to `XRRGetProviderInfo'
.../xrandr.c:3404: undefined reference to `XRRFreeProviderInfo'
collect2: error: ld returned 1 exit status

I guess I'm missing some header files somewhere? But i'm not sure what
and autoconf didn't pick up on anything.

Cheers,
Sam.
