New description:
As with pari (#12315), on OS X Lion, if you set SAGE_CHECK=yes and build
gsl, some tests fail. If we set `SAGE_DEBUG=yes`, which uses `-O0`
instead of `-O2` as a compiler flag, then self tests all pass. Modifying
the spkg to use `-O1` instead of `-O2` also makes all tests pass. So a
possible fix for spkg-install:
{{{
