After initial failure I did try adding this:

    } elseif {${MAJOR} == 10 && ${MINOR} == 6 &&
              [llength ${qt_arch_types}] == 1 &&
              [lsearch -exact ${qt_arch_types} ppc] == 0} {

        configure.args-append -carbon
        configure.args-delete -optimized-qmake

    }

But it still fails. Any ideas?

16. S. I recall it also failed on 10.6 PPC, but I did not tried to fix it there. The current issue refers to 10.6.8 Rosetta, not 10.6 PPC.

Ok, apparently macosx_deployment_target 10.5 is needed in addition to the above change.
