Hi
apt-get does even more: eg build-dep - Configure build-dependencies for source packages
You can do that with yum-buildep which is part of yum-utils in Fedora Extras
but sadly its future here is limited. NIH problem one suspects.
Nope. Real issues like lack of multi-lib capability. See http://fedoraproject.org/wiki/Tools/Apt
