So for example, there is one PortIndex for Darwin 12 Intel. There is not currently a separate PortIndex for Darwin 12 Intel with libc++, so anyone with e.g. OS X 10.8 with libc++ syncing from the rsync server will see the version of this port as 3.20.2 not 3.18.3 when querying the index, for example when running port info or port outdated. If we're going to change Portfile attributes such as version that get stored in the index based on the C++ library, and I agree this is a situation that would arise more and more as newer versions of software require libc++, should we make a separate libc++ PortIndex for 10.6/10.7/10.8?

One suggestion was to add cxx_stdlib as a variable in archive_sites.conf, and upload the libc++ archives with the same names as the libstdc++ archives but in a new subdirectory, e.g. https://packages.macports.org/libc++/.

Some time back I opened a ticket at
    https://trac.macports.org/ticket/50448
During the MacPorts meeting the suggestion was to start using a
different path/prefix, to add an additional variable to the database
(and certainly not to mix this with changes of the compression
format).

We could brainstorm (or at least summarize the discussion happinging
on the mailing list) in that ticket.

(I admit that I wasn't even aware that this could also be a problem
for PortIndex.)
