It would be helpfull for everyone with slow downstream to change to the tar.xz source files. Upstreams offers them both in tar.bz2 and tar.xz - also it decompresses faster than bz2. thanks.
what is the size of each file and how long does it take to decompress on your system?
fetching takes ~8 minutes (40mb) unpacking on my old pc: real 1m47,911s user 1m10,865s sys 0m13,537s unpacking on my new pc: real 0m8,081s user 0m7,141s sys 0m0,698s xz would save ~2 minutes there is no need to change it on the fly, but would be great to fix this for the next release.
