Confuddled: How do I build gnome 2.22?

[Anders Lindgren <ali%df.lth.se@localhost>]

[ fresh install of 4.99.72 on port-i386 ]

After joyfully getting 4.99.72 with wapbl-logging (yay!) and all onto my 
eeepc900, I thought I'd set up an old workhorse -- an old dual PIII -- to 
build pkgsrc packages for it and try out gnome 2.22 before [more or less] 
reinstalling all the packages on my main desktop. So I grabbed 
pkgsrc-2008Q2 and went about it..

I found meta-pkgs/gnome-platform is the package for getting the 2.22 core 
libraries. The rest of the gnome desktop still seem to be lumped together 
in the meta-pkgs/gnome package for gnome 2.18.1. It depends on gnome-base, 
which appears to be some minimal set of gnome 2.18.1, and to a large 
extent overlaps with what is now in gnome-platform for 2.22 -- so I 
figured if I build gnome-platform first (to get the 2.22 core libraries) 
and then gnome to get the rest, gnome-platform would satisfy (thanks to 
">=...") most of the dependencies in gnome-base, and it should Just 
Work(tm). So much for trying to reason... :-)

While gnome -> gnome-base is building wm/metacity, I now get:

---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---

checking for METACITY... configure: error: Package requirements (gtk+-2.0 
> = 2.10.0 pango >= 1.2.0 gconf-2.0 >= 1.2.0 libstartup-notification-1.0 >= 
0.7 xcomposite >= 0.2 xfixes xrender xdamage xcursor) were not met:

No package 'xdamage' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables METACITY_CFLAGS
and METACITY_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---

I don't know if this error has anything at all to do with 
meta-pkgs/gnome-platform, but I figured someone here must have tested 
building a gnome desktop. What am I doing wrong here? Should I install 
gnome 2.18.1 first and then try to replace all the core libraries by 
forcing an install of gnome-platform, or what is the intended way to 
install gnome 2.22?

Grateful for any help.

Best regards,
