asterisk users - Apr 2010 - Dahdi will not compile on Unbuntu Studio Linux 9.10 (Karmic) 32bit

Been trying to get this to go but nongo :-).

I'm asking for some guidance especially if I should not be doing this on
an RT kernel.

I've installed what is supposed to be all of the requred deps.
Some factors that may be adding to my problem are:

1. this is only a test.. it's a 32bit guest OS running in VMware
   under a 64 bit windows host.. (although I'be compiled it on other 
distros in this config without issues.

2. This is ubuntu Studio which uses an RT (realtime kernel)..
There seems to be very little aout there regarding running asterisk on
RT linux... one woudl think this would have some benefits..
Big benefits.. I've always wondered.
But moreso in a nn-virtual machine environment.

Asterisk builds just fine and works.

Kernel is :  2.6.31-9-rt (buildd at palmer) (gcc version 4.4.1 (Ubuntu
4.4.1-4ubuntu8) ) #152-Ubuntu SMP PREEMPT RT Thu Oct 15 05:01:14 UTC 2009

Install is Ubuntu Studio 9.10 (Karmic) 32bit
and up to date.

I have not yet tried it on a stand-alone machine..
I don't think that will be the fix but I will try that soon.

RT kernels don't have traditional mutexes, which are used in various
places in DAHDI for Linux. To my knowledge nobody has done the work to
update the drivers to be able to use the RT kernel replacement
synchronization mechanisms when compiled against an RT kernel.
