armadillo @7.400.1: #error "*** Need a newer compiler ***"

[ryandesign (Ryan Carsten Schmidt)]

armadillo fails to build on Snow Leopard, saying it needs a newer compiler:

Old incompatible compilers should be added to compiler.blacklist, and MacPorts will choose a different one.

It took a bit of experimentation, as I wasn't too familiar with the compiler.blacklist, but r151421 seems to have fixed this.
