The comment in configure.in says this:

# Check we have GNU sed: some of the stuff done by "make install" relies
# on some pretty fancy sed expressions, and AIX sed doesn't produce the
# same results, causing install to fail

I don't know what the fancy expressions are.  If it's holding you up
with Darwin, you could just comment out the check (with an
explanation) and we can fix it up later...
