asterisk users - Jul 2010 - Dahdi 2.3.0.1 fails to compile in Xen DomU

Greetings list,

I've compiled and installed dahdi countless times on standalone machines, 
but recently I've been trying to compile Dahdi in a Xen DomU without much 
success. The errors I'm seeing are as follows:

/var/tmp/portage/net-misc/dahdi-2.3.0.1/work/dahdi-linux-2.3.0.1/drivers/dahdi/zaphfc/base.c:1689:
error: 'modes' undeclared (first use in this function)
/var/tmp/portage/net-misc/dahdi-2.3.0.1/work/dahdi-linux-2.3.0.1/drivers/dahdi/zaphfc/base.c:1689:
error: (Each undeclared identifier is reported only once
/var/tmp/portage/net-misc/dahdi-2.3.0.1/work/dahdi-linux-2.3.0.1/drivers/dahdi/zaphfc/base.c:1689:
error: for each function it appears in.)
/var/tmp/portage/net-misc/dahdi-2.3.0.1/work/dahdi-linux-2.3.0.1/drivers/dahdi/zaphfc/base.c:1689:
error: 'modes' undeclared here (not in a function)

etc.

The DomU in question is running Gentoo Linux with a 2.6.34 Xenified kernel. 
I've tried stepping back to 2.6.32 and 2.6.31 kernels, as well as dropping 
dahdi back to 2.3.0 and 2.2.0, all without success.

I wouldn't be in the slightest bit surprised if I'm missing a kernel
option
somewhere, but I'm not sure where to start (or how best to diagnose such 
things). Is there a list of "required kernel options" for dahdi
published
anywhere I could consult, or has anyone else come across similar errors 
before?

Any suggestions gratefully appreciated.

Thanks in advance.

Regards,

Chris

zaphfc? From where exactly?

IIRC the one in my Debian package builds OK with 2.6.34. Haven't tried
Xen, though.
