issues installing comedi 0.7.68 and CVS

I have tried upgrading to comedi 0.7.68 and also the latest CVS version and have had similar troubles with both that I didn't have with comedi 0.7.67. 

I'm running a fairly old red hat linux 2.4.4-rtl (and I see about comedi not being supported on red hat), with rtlinux 3.1 patch.

To install comedi 0.7.68/CVS, I had to bump up my revision for automake and autoconf.  I've done that, and am now running 
automake 1.7 and autoconf 2.56

One apparently minor issue is a compile error reported in usbdux.c. I don't need this driver so I commented out the offensive line, ok?

usbdux.c: In function `usbduxsub_probe':
usbdux.c:2245: structure has no member named `speed'
usbdux.c:2245: `USB_SPEED_HIGH' undeclared (first use in this function)


Other than this, the comedi 'make' 'make install' work fine.  I can install all my drivers (via modprobe) and kcomedlib without any hitches, as before.  

The biggest trouble encountered is when trying to run the ./comedi_config from comedilib_0.7.21, where I get a segmentation fault:

./comedi_config /dev/comedi0 ni_pcimio
1288 Segmentation Fault

I originally didn't have this problem with comedi 0.7.67/comedilib 0.7.21.

Do I need to use the latest version of comedilib from the CVS together with the latest version of comedi (or 0.7.68), or should I be able to use the one I have now (0.7.21)?

Any other ideas for the fault?

I have also tried re-installing the older version of comedi-0.7.67 and am receiving all sorts of unresolved symbol errors in /lib/modules/2.4.4-rtl/comedi, and also a modprobe on kcomedilib 0.7.67 now reports unresolved symbols.
