Im using the following command:
rpmbuild -ba --target=i586 SPECS/myspec.spec

I just tried to build on a native 32bit Linux and see what happens. The
problem here is, I cannot deploy the packet on the same machine I build
it on. That means the machine that build the goddamn thing doesn't
satisfy it's own requirements? WTF?
This is the output of rpm -qRp

Huh? I remember reading the day before that rpm uses some magic that
involves invoking ldd on the binaries to generate the dependencies.
Maybe this information was outdated?
