Problem installing GTK20

[Olivier Nicole]

Hi,

It seems that it is a problem that appeared before, but the suggested
workaround did not work.

When trying to portupgrade gtk, I get the error:

checking Pango flags... gnome-config: not found
configure: error: 
*** Pango not found. Pango built with Cairo support is required
*** to build GTK+. See http://www.pango.org for Pango information.

I tried to reinstall cairo and pango, but pangocairo is always missing:

pkg-config --exists pangocairo
gnome-config: not found

I just cvsup'ed so I should have the very lasted stuff.

What do I do wrong?

TIA,

Olivier
