Comment (by kencu):

 no, that's not it, I think. On 10.5 PPC, the build fails similarly.

 Linking it manually also fails.

 {{{
 $ libtool -lSystem -dynamic -install_name ${prefix}/lib/libgnuregex.dylib
 -o libgnuregex.dylib regex.o
 ld: symbol dyld_stub_binding_helper not defined (usually in
 crt1.o/dylib1.o/bundle1.o) for architecture ppc
 fatal error: libtool: internal link edit command failed
 }}}

 that symbol is supposed to be found in libSystem, and it is there:

 {{{
 LeopardG5:regex-0.12 $ nm -a -arch ppc /usr/lib/libSystem.dylib | grep
 dyld_stub_binding_helper
 000b25c4 t dyld_stub_binding_helper
 }}}

 Hmm. libtool weirdness.

 Ignoring libtool,and changing the link command to this, does work:

 {{{
 post-build {
     system -W ${worksrcpath}
 "MACOSX_DEPLOYMENT_TARGET=${macosx_deployment_target} ${configure.cc}
 -lSystem -dynamiclib -install_name ${prefix}/lib/libgnuregex.dylib -o
 libgnuregex.dylib regex.o"
 }
 }}}


 As to exactly why libtool is not working, not sure -- we have libtool
 experts around MacPorts who would know better than I do.
