Restarting from scratch on Snow Leopard

> One question about setting clang-5.0 as the default compiler. Do I have to repeat the whole LibcxxOnOlderSystems procedure or is it enough to install clang-5.0 (hoping it will install) and then change macports.conf to look something like this?

You will hopefully _never_ have to do LibcxxOnOlderSystems again, unless you explode your MacPorts installation. Not a bad moment to back that up, BTW.

Yes, you can just set your default compiler to anything to you want now.

clang-5.0 is good -- I think probably best. IF you want to see 1000 errors / port, try setting it to clang-7.0 :>

You will almost certainly not be finding new issues -- just old issues we haven't fixed yet.

The one you're mentioning is most likely the error we see when the libunwind headers are installed. gcc builds will fail in that case.

Gotta get around to fixing that.
