What version of XCode are you using? It is highly recommended to
install the latest supported XCode for 10.4 and XCode 3 for 10.5. and
build Sage from sources if you want to do development. Once you did
the full build you can usually upgrade in place. Even with a binary it
is highly recommended to do a "sage -ba" before cloning. If you did
build from source something went wrong, so we should be given access
to the build logs, i.e. gzip them and upload them somewhere, then post
a link here.
The error about MACOSX_DEPLOYMENT_TARGET being set to 10.1 doesn't
ring any bells, but my guess would be that your xcode is too old.
Cheers,
Michael
