emerge of parted-1.6.6 fails as it cannot download the source. I'm guessing GNU has moved it somewhere. Reproducible: Always Steps to Reproduce:
apparently, GNU people are checking the authenticity of the tarball, and have made it unavailable. it'll be back "real soon now" according to them (on Aug 2). Meanwhile, I'll see if I can get a copy onto our own mirrors
thanks to nate in #gentoo, I have put a parted-1.6.6. tarball on our mirrors now -- it should sync up in about 30 minutes or so.
