Add some mirrors to /etc/yum.conf; look at
http://fedora.redhat.com/download/mirrors.html and select several that
are near you.  For example, you might have:

[development]
name=Fedora Core $releasever - Development Tree
baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/development/$basearch/
        http://ftp.dulug.duke.edu/pub/fedora/linux/core/development/$basearch/
        ftp://ftp.dulug.duke.edu/pub/fedora/linux/core/development/$basearch/
        ftp://ftp.linux.ncsu.edu/pub/fedora/linux/core/development/$basearch/
        ftp://mirror.cs.princeton.edu/pub/mirrors/fedora/linux/core/development/$basearch/
        http://distro.ibiblio.org/pub/linux/distributions/fedora/linux/core/development/$basearch/

But replace the URLS with mirrors that are close to you.

Yes, setenforce is just a utility that does the same thing.  The
advantage of using setenforce rather than directly writing to
/selinux/enforce is that if we change the mount point for selinuxfs,
setenforce will automtically pick up the new location (via libselinux).
