I had that happen as well before I completely cut up the buildinstall script. I seem to recall that the usage line is actually a misnomer and you're probably passing some weird parameter which buildinstall doesn't like. I ended up echoing the buildinstall to stdout and trying to run it by hand. The problem here is that it's trying to re-execute buildinstall again from inside of the other RPM. Basically it's a gigantic pain in the ass. One of these days I'll get around to properly releasing my "Build anaconda in a chroot environment" python script. --Patrick.
