Comment (by leif):
Replying to [comment:66 leif]:
> `patches/configure.patch` is pretty unreadable, and as far as I can see
`SPKG.txt` doesn't mention Clang at all (except for John's changelog
entry, which says we shouldn't [or now do not] use it...?).

In `spkg-install`, we have:
{{{
#!sh
Darwin)
# In some cases (see SAGE_ROOT/spkg/bin/sage-env), on Darwin,
# CC might be set to clang, but MPIR doesn't seem to build
# with clang.
CLANG=`command -v clang`
GCC=`command -v gcc`
if [ -n "$CC" ] && [ "$CC" = "$CLANG" ] && [ -n "$GCC" ] ; then
export CC="$GCC"
fi
}}}
Which means we use `$GCC` even if `CC` is set to `clang` (actually, the
output of `command -v clang`) ''if GCC is available'' (more precisely, if
`command -v gcc` is non-empty).
Apart from that these tests are pretty limited [to not say broken] (and
`CC` is always set btw.), that doesn't prevent the use of Clang. So we
should either issue an error message if GCC is not available (while
`command -v gcc` might actually give a link to `clang` :-) ), or we should
fix the build(?) issues with Clang...
