I think we are still waiting for the final ppl release, but otherwise
I agree that
instructions and tarballs should be provided rather yesterday than tomorrow.
I don't necessarily agree with statically linking libstdc++ into cc1 - do you
expect problems with linking dynamically?  Static libraries for libgmpxx or
ppl or cloog are usually not available due to size and their libstdc++
requirement.
