xserver xorg build for IRIX?

[Bill en Dennis]

I attempted to build xserver xorg under IRIX and got this error:

checking whether to build Xorg DDX... yes
checking whether to build Xgl DDX... no
checking whether to build Xegl DDX... no
checking whether to build Xglx DDX... no
checking for dlopen in -ldl... yes
configure: error: Your OS is unknown. Xorg currently only supports
Linux,               Free/Open/NetBSD, Solaris, and OS X. If you are
interested in porting           Xorg to your platform, please email
xorg at lists.freedesktop.org.

Is there any way to build it other than using one of the supported systems?
