I  had this problem  with Solaris  10 too  (a preview  release. I
didn't check again but I  think it's still true with the official
release).

It's a little bit more complicated but the effect is the same.

The problem is  that gtk describes its own  dependancies in a way
that  is problematic  in  some pretty  rare  occurrences (in  the
gtk+-2.0.pc file).

I do not  have anymore the configuration to  reproduce it but try
to play  with pkg-config  and the light  will come (try  with and
without the following patch and it will become obvious).

He he. Mee too.

    Laurent> Any ideas ?

See patch  below. This patch  have to be applied  before building
gtk (yes the C version).


Have a look at the following bug report:
 http://bugzilla.gnome.org/show_bug.cgi?id=165499

It would  be nice if you  can reproduce it and  explain it better
than  me,  quite like  you  have done  in  your  mail and  adding
pkg-config outputs.

Hope that helps,

     Vincent
