KDevelop (Gideon) doesn't compile

[Sebastian Gutweiler <sebastian@gutweiler.net>]

Hi,

I tried to compile Gideon from CVS, but it always aborts with many
errors like that one: 

index.docbook:1392: validity error: No declaration for element book
</book>

I searched a little bit and found the advice to set KDEDIR and KDEDIRS.
So I set these to /usr/bin (I have the 3.0.4 Debian packages installed). 

Thank you,

Sebastian
