GTK/theme error, please reply ASAP

["Kenneth Christiansen" <kenth writeme com>]

I downloaded themes-gtk+ from CVS, and when i try to compile GTK+
I get this error:

making all in gtk

What's wrong, and what can I do?

if this is a problem in the CVS source and someone fix it. 
what am I going to write to update it? I got it this way:

cvs -ez3 get -r themes-2 -d themes-gtk+ gtk+

Thanks, Daleak.
