I did some more digging into this, and I am not so sure that this is a bu=
g
in SConsAddons but rather a shortcoming of the installation directory
structure currently in use. In any event, I added some more instructions =
to
the README file for post-0.7.8 releases.

The 0.7.8 version of how to build on Mac OS X is as follows:

   On Mac OS X, the build may auto-detect that it can build multiple
   architectures (not necessarily universal binaries), but this case is n=
ot
   currently handled well. SCons will complain that there are multiple wa=
ys
   to build the same target and exit with an error. To work around this,
   specify the desired architecture explicitly (pass var_arch=3Dppc,
   var_arch=3Dia32, or var_arch=3Dppc64 on the scons command line) and di=
sable
   universal binary compilation (pass darwin_universal=3Dno). For example=
, to
   target PowerPC alone, use the following command:

      scons var_arch=3Dppc darwin_universal=3Dno

   Otherwise, build a universal binary:

      scons var_arch=3Duniversal darwin_sdk=3D/Developer/SDKs/MacOSX10.4u=
=2Esdk
