I am unable to compile kde3/4 or gnome in /usr/pkgsrc/meta-pkgs/.

I get errors at hiemdal (kde) and automake (gnome). I can see patches in
pkgrsc, how do I patch it before compiling. I cant find kde3 @ pkg_radd.

I prefer building individual packages instead of meta-pkgs, how to find out
dependencies for kde install.
