5. Link problems with Xdmx, may be Darwin-only(?)

To recreate:
Enable the Xdmx options in your [build/]config/cf/host.def file,
e.g.
#define XdmxServer YES
You also have XFree86Devel set to YES.
Build with latest XCode (Apple-provided gcc, ld, etc.).
Possibly related env-vars:
export MACOSX_DEPLOYMENT_TARGET="10.4"
export SDKROOT="/Developer/SDKs/MacOSX10.4u.sdk"
export SDK="${SDKROOT}"
...and maybe others...
$ gcc --version
powerpc-apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple Computer, Inc. build 5367)

Discussion:
Some libs aren't being included at all during the link phase for
Xdmx.
I _think_ this is how it might be fixed:

No. Xdmx has its own GLX implementation.
The patch below should fix this:
