 > Assigning to maintainer. Is pango active? Do you have
 /opt/local/lib/pkgconfig/pangox.pc?

 Sorry I had pango @1.20.5_0+no_x11 so no pangox.pc. After installing pango
 @1.20.5_0 (with x11) pangox.pc is found, but graphviz's build fails with
 following

 {{{
 Package pangocairo was not found in the pkg-config search path.
 Perhaps you should add the directory containing `pangocairo.pc'
 to the PKG_CONFIG_PATH environment variable
 Package 'pangocairo', required by 'GDK', not found
 }}}

 $ port search pangocairo[[BR]]
 No match for pangocairo found
