 I cannot modify someone else’s ticket, so opening a new one. `gnuregex`
 builds for ppc (Leopard and Snow Leopard) with this change to its
 portfile:

 {{{
 post-build {
     set command "libtool -lSystem -ldylib1.10.5.o -dynamic -install_name
 ${prefix}/lib/libgnuregex.dylib -o libgnuregex.dylib regex.o"
     ui_debug "$command"
     system "cd ${worksrcpath} && ${command}"
 }
 }}}

 In particular, `-ldylib1.10.5.o` is to be added.
 Discussion here: https://trac.macports.org/ticket/52466

 P. S. I can check on Tiger whether `-ldylib1.10.4.o` works later on.
