It has a single statically linked binary. Which probably means it already=20 contains everything you will need and will run just fine. No need to build= =20 everything multilib; if you do need a 32bit lib, just install the appropria= te=20 emul-x86-linux package. =2D-=20 alan dot mckinnon at gmail dot com
