That's probably not actually the index being broken, but a circular
dependency. See <https://trac.macports.org/ticket/59289>.

The issue causing the circular dependency is that all the system
compilers are blacklisted by whatever port you're building, and the
compiler selection is falling back to macports-clang, which doesn't work
out of the box on libstdc++ platforms. This should be fixed in MacPorts
2.6.2.
