[Asterisk-Users] do not appear to have the sources for the 2.6.11.4-20a-default kernel installed

[Angus Comber]

When I attempt to compile the zaptel driver (latest CVS HEAD) I get this 
compile error:

You do not appear to have the sources for the 2.6.11.4-20a-default kernel
installed.
make: *** [linux26] Error 1


When I load YaST I see kernel-source 2.6.11.4 as installed version.  So why
do I get this message?  YaST is just a SUSE config menu program.

What can I do?

I am running SUSE Pro 9.3 and have today updated using YaST.
