 The build (outside of Sage) '''works'''.

 Replying to [comment:17 zimmerma]:
 > is this a 32-bit machine?
 Well, technically the processor is 64-bit capable (I believe) but it runs
 a 32-bit system and {{{gcc}}} produces 32-bit code by default.

 > What does ECM config.guess return?
 powerpc-apple-darwin8.11.0

 Can you try the svn version of
 > GMP-ECM using {{{svn checkout svn://scm.gforge.inria.fr/svn/ecm}}}?
 This '''works'''.

 > Please can you check it works correctly with this patch?
 This '''works'''.

 Replying to [comment:21 leif]:
 > Setting `ABI=32` would perhaps also work.
 No, it does '''not'''.
