gimp fails to detect gtk2 version

[rmottola (Riccardo)]

on 10.6 when building gimp +quartz (about as I always did) it fails to recognize gtk2

  - Error: missing dependency gtk+-2.0 >= 2.24.32
      *** Test for GTK+ failed.

however I have this installed:

The following ports are currently installed:
  gtk2 @2.24.33_3+quartz (active)

and... 2.24.33 is > 2.24.32

What's going wrong? log attached

looks like perhaps some of your pango / cairo / harfbuzz / etc testing might have left you with some mismatched libs?

Either install the right version of libpangocairo, or rebuild gtk2 against this version, if you want to keep this version installed.

this is some sort of chicken-and-egg problem. rev-upgrade detects a rebuild of gtk2:

 gtk2 @2.24.33+quartz
 py27-pygtk @2.24.0+quartz
 librsvg @2.54.5
 appstream-glib @0.8.2
 gtk-osx-application-gtk2 @3.0.1
 gimp2 @2.10.32+python27+quartz

but it starts rebuilding gimp2... which fails. What is the best way to force an upgrade? I did try to "build and install@ gtk this way:

sudo port -v build gtk2 +quartz
sudo port -v install gtk2 +quartz

This is suboptimal, because it will set this port as requested and one must match the variants, but also because it does not work: as install ended rev-upgrade still detected gtk2 as broken. How can I best force an upgrade rebuild?
