The MacPorts project has never had any PowerPC build machines, so we have never offered any binary packages for PowerPC. If you have "clang-3.4-3.4.2_9+analyzer.darwin_9.ppc.tbz2" on your system, it's likely it was build on your own system.

"I/O error" often means you have a problem with your disk. You should verify your disk with Disk Utility.

It sounds like the clang-3.4-3.4.2_9+analyzer.darwin_9.ppc.tbz2 file you have is corrupt, possibly because it is truncated, or possibly because it cannot be read due to the I/O error. Once you've verified your disk is ok and has enough space, run "sudo port clean --all clang-3.4 && sudo port uninstall clang-3.4". Then build it again on your own system using "sudo port install clang-3.4".
