Error running the configure script

[Sandro Coretti <corettis student ethz ch>]

hi folks,

i've been trying to install gtk 2.10.11 but was stopped by a problem that 
apparently many others had as well but thus far, none of the numerous posts 
on the internet containted much that could help me.

the configure script aborts saying that it can't link to pango, specifically

checking Pango 
flags... -I/usr/local/include/pango-1.0 -I/usr/local/include/glib-2.0 
-I/usr/local/lib/glib-2.0/include -I/usr/local/include/cairo  
-L/usr/local/lib -lpangocairo-1.0 -lpango-1.0 -lcairo -lgobject-2.0 -lgmodule-2.0 -ldl -lglib-2.0
configure: error:
*** Can't link to Pango. Pango is required to build
*** GTK+. For more information see http://www.pango.org


below i added the corresponding lines of the config.log file

judging by these unresolved references to some functions, which i guess belong 
to the pango library, changing the order of -lpango-1.0 and -lcairo in the 
gcc call might help. but i'm neither sure about that nor do i know how to 
achieve that.

i'd be happy if some could give me some pointers on this one.

thank you very much
