mcpp's universal variant fails on Snow Leopard:

Looking in the portfile, it's hardcoded to use the 10.4u SDK and the i386 and ppc architectures! This is not going to work on Snow Leopard. MacPorts provides a slew of variables pre-defined with all the values you need to build universal on the currently-running version of Mac OS X. Please use these instead of hardcoding.

What changes do you suggest to make to the Portfile?

[jmroot (Joshua Root)]

Try this.

[blair (Blair Zajac)]

Thanks for the patch. Do I need to bump the revision number for this?

[ryandesign (Ryan Carsten Schmidt)]

Ah well, it only affects non-default installs (universal and non-default build_arch), so I might not ordinarily bump the revision, but it only takes under a minute to build, so it's probably not a big inconvenience to bump the revision anyway.

[blair (Blair Zajac)]

Thanks! Fixed in r67857. I updated the rev also.
