Comment(by ryandesign at macports.org):

 OpenSceneGraph 2.4.0 builds on Tiger but on Leopard it fails with:

 OpenSceneGraph 2.6.1 builds on Leopard but on Tiger it fails with:

 I expect this entry from the ChangeLog is relevant:

 {{{
 2008-05-08 12:55 +0000 [r8283]  robert:

         * From Philip Lowman, "Attached is a patch to the toplevel
           CMakeLists.txt which adds an automated test for
           OSG_GLU_TESS_CALLBACK_TRIPLEDOT. This should help ease initial
           configuration on OS X systems."
 }}}

 Need to check whether the newest development version already fixes this.
 If so, we can try to get a patch. If not, we need to report the problem
 upstream.
