Comment (by Peter_Dyballa@…):

 Replying to [comment:4 jeremyhu@…]:
 > `__Unwind_GetIPInfo` should be provided by /usr/lib/libgcc_s.1.dylib
 when building with /opt/local/bin/g++-apple-4.2 on Tiger/ppc

 This symbol is not contained in /usr/lib/libgcc_s.1.dylib! It contains for
 example

 {{{
 9143ab58 T __Unwind_GetIP
 00000000 a __Unwind_GetIP.eh
          U __Unwind_GetIP
          U __Unwind_GetIP
 }}}

 Similarly in /Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libgcc_s.1.dylib:

 {{{
 90bf7640 T __Unwind_GetIP
          U __Unwind_GetIP
          U __Unwind_GetIP
 }}}

 >
 > Please verify that the symbol exists in /usr/lib/libgcc_s.1.dylib and
 also check the link line (-Wl,-v) to figure out why it's not picking it
 up.

 > Does it work if you force -mmacosx-version-min=10.4 ?

 How and where can I add these additions? I don't understand the Portfile
 language well…

 When I understand the Portfile correctly, then it tries to build linstdcxx
 from GCC 4.9.
