> Is MACOSX_DEPLOYMENT_TARGET set in the environment when you run the command that gives the error message?
I don't think I had this environment set when I saw the above error 
message. I had to set MACOSX_DEPLOYMENT_TARGET=10.5 in order to 
workaround it though.

BTW, I just figured that following command will reliably reproduce this 
issue:

$ MACOSX_DEPLOYMENT_TARGET=10.3 python2.7 -B -s -c "import 
sys;print('%d.%d' % tuple(sys.version_info)[:2])"

IOError: $MACOSX_DEPLOYMENT_TARGET mismatch: now "10.3" but "10.5" 
during configure

Though, I do recall seeing this error without having that environment 
set at all.
