I noticed that we now have a Bz2 packer in the Pike tree. (Good job Andreas!)
I did some work to get it to compile with my libbz2, and now it compiles and links fine.
However, it segfaults on my machine and on some machines in xenofarm it gives funny errors in the testsuite (hence all the new yellow dots). I'm out of debugging tokens for today, so I don't mind at all if someone else makes it work... :)
