problems building x11-toolkits/gtk20 (gtk-2.3.6)

[Fernando Durango]

Hello all,

I am having trouble building gtk-2.3.6 on 5.2.1-RELEASE running
portupgrade x11-toolkits/gtk20. Currently Gnome 2.5.5 is installed and I
would like to upgrade to 2.6beta1. Ran ./marcusmerge -a, then portupgrade
-r pkgconfig, which died on gtk-2.3.6. Trying to build it by itself fails
with the same errors:

make  install-data-hook
/bin/sh ../../mkinstalldirs /usr/X11R6/etc/gtk-2.0
../../gtk/gtk-query-immodules-2.0 > /usr/X11R6/etc/gtk-2.0/gtk.immodules
Cannot load module /usr/X11R6/lib/gtk-2.0/2.2.0/immodules/im-gucharmap.so: Shared object "libpango-1.0.so.300" not found
/usr/X11R6/lib/gtk-2.0/2.2.0/immodules/im-gucharmap.so does not export GTK+ IM module API: Shared object "libpango-1.0.so.300" not found
*** Error code 1

Any ideas what could be wrong? pango-1.3.6 is currently installed.

TIA,
