Afair I'm using PORTAGE_BZIP2_COMMAND with lbzip2 and it works fine. Also some time ago I've changed a bit the (famous?) stage4 backup script from g-wiki to support parallel gz/bz2 implementations (simple check if there pbzip2/lbzip2/foobar installed and if yes, use it instead of normal gzip/bzip2). Maybe portage should be like my stage4 mod? If it finds some parallel (de)compressor it should use it, if not fallback to standard gzip/bzip2?
