I'm gettin errors when I run the see-through HMD calibration routines on
the PC version 2.11.  after "right clicking" as per the docs, the
argCalibMainFunc(void) runs (from gsub.c), but the arVideoGetImage
function call is commented out, so the dataPtr is null when sent into the
following functions.  

In fact, the arVideoGetImage() in gsub.c isn't implemented at all, and
just returns NULL, even if it was called.

am I misunderstanding someting?  or do i need to do some cutting and
pasting to get this stuff running correctly?

thanks!

Is your code in argCalibMainFunc(void) different from following code?
Actually arVideoGetImage() is not commented out.
If your code really don't have this part in argCalibMainFunc(void),
It would be wrong one. Please download it again.

#ifdef __sgi
    if( (dataPtr = (ARUint8 *)arVideoGetImage(did)) == NULL ) {
        sginap(1);
        return;
    }
#else
    if( (dataPtr = (ARUint8 *)arVideoGetImage()) == NULL ) {
        return;
    }
#endif
