The next thing is to look at the Sage sources (especially spkgs and scripts in $SAGE_ROOT/local/bin I guess), in order to make Sage build on 10.7 when the XCode issues local to the system are fixed. I don't know how many, but there are pieces of code in Sage that assume any Darwin != 10 must be either 8 or 9 (i.e., MacOS X 10.4 or 10.5). For shell scripts, one should perhaps search for 'uname -r' and 'sysctl' (or 'kern.osrelease') and make sure there's a proper "less than" or alike. I've fixed one instance of that in the MPIR 2.1.3.p3 spkg (#8664) just a few days ago.
