Problems while compiling xorg on Ubuntu

[pplive]

Dear all,

I try to compile xorg according to the following instruction:

http://www.x.org/wiki/Building_the_X_Window_System/

When I tried to execute "./util/modular/build.sh --clone $HOME/build",
I have received the following error information:

sis_driver.c: In function 'SiS_GetSetBIOSScratch':
sis_driver.c:14022:8: warning: 'xf86MapVidMem' is deprecated (declared

Can somebody provide me some hints? My system is Ubuntu 13.10.

Thanks so much!

Best regards,
