And does using llvm-gcc-4.2 work?

[browntroutstream@…]

Yep, that works. Thanks.

It's needed for ginac and cgal as well. Looking through the recent tickets for Lion it appears that this is a common "fix".

Ok, fixed in r87105.

It's needed for ginac

Ok, fixed in r87106.

and cgal as well.

See #31562.

Correct. Many software packages are not ready for the clang compiler. As these are discovered, they can be updated or fixed or made to use a different compiler.

Reverted in r98227 since it's no longer necessary with cln 1.3.2.

Ok, fixed in r87106.

Reverted in r98228 since it's no longer necessary as of GiNaC 1.6.0.
