svndigest @0.11 fails to build on Mac OS X 10.7.x only, because it tries
to run each of the three executables during the build, and they crash:

Mac OS X 10.7 was the first version to include libc++. It's possible it
has a bug that was fixed in later versions. The build succeeds on OS X
10.8 and later, and also on Mac OS X 10.6 on which we install our own
newer libc++.
If this is a libc++ bug and not a bug in svndigest or yat, one solution
that might work is to use the legacysupport portgroup and tell it to use a
newer MacPorts libc++:
{{{
PortGroup legacysupport 1.1
}}}
{{{
legacysupport.newest_darwin_requires_legacy 11
}}}
{{{
legacysupport.use_mp_libcxx yes
}}}
If svndigest is passing around C++ objects between itself and its
dependencies, this isn't a good idea, but if svndigest is only using C++
objects it created itself and doesn't share them with other libraries,
this might be fine.
