Klamav Installation Problem

[Old Rocker]

I'm trying to install the KDE gui front end to the Clam Anti-Virus 
package, Klamav, which is not yet in the ubuntu repositories.

As it comes in a tarball, I first installed  build-essential, but then 
the tarball extracted to an installer script.  When clicking on that, a 
console came up and installed a gui installer, which said that I needed 
two dependencies, Dazuko and Clamav.  However, when it started up the 
installer failed with the following log entry:

***** Dazuko
***** Running configure (./configure)...
checking host system type... Linux
checking for make utility... ok (make)
checking for C compiler... ok (cc)
kernel source in /lib/modules/2.6.12-10-386/build... no
kernel source in /usr/src/linux... no
error: kernel source files not found
***** Return value 1

Does ubuntu keep its kernel source in another place other 
than /usr/source/linux?  And how do I install Klamav?
