Summary:                    KVERS does not allow to build DAHDI for another
kernel any more
Description: 
Setting KVERS used to allow building DAHDI for a kernel version different
from the current kernel.

It stopped working several months ago.

I tried to set KSRC in addition to KVERS.  It did not help.

You do not appear to have the sources for the 2.6.32-22-generic kernel
installed.
make: *** [modules] Error 1


Granted, the error message in that case appears to be off because I didn't
ask it to build against 2.6.32-22-generic (and that is completely driven
off the presence of the KVERS variable, which I didn't pass), but the
presence of the .config file in the KSRC directory is what the makefile is
using to control the build.
