Right now, the package installer is supposed to only run on SL, and will overwrite an existing libc++ and libc++ABI library if there is one (but there's only one version, at the moment, so that would not seem to be a big issue).

Your installer exits without doing anything if the OS is not 10.6, so that's good. No danger of messing up later systems.

The app on the disk image already contains a number of libraries, like boost, in the Contents/Frameworks directory. Could you put libc++ and libc++abi in there too, thus making an installer that modifies the OS unnecessary?

The libcxx port in MacPorts also modifies the OS, so there is precedent for that, even if it feels messy to me.
