Hi, I ran into one problem worth mentioning while recompiling gtk and its dependencies as universal libraries using macports: the pango port refused to build with +universal (it fails when trying to merge the i386 & x86_64 libs). The pango-devel port does work with one small tweak as described at https://trac.macports.org/ticket/22801.
Essentially, I had to comment out the "PortGroup muniversal 1.0" line in the Portfile to get a working universal library for pango. -Sudish On Mon, Jun 21, 2010 at 5:09 AM, Giuseppe Luigi Punzi <glpu...@lordzealon.com> wrote: > I died in more dependencies.
