Here is a small audio/video HOWTO on RPM building packages and setting up a user space build environment.

If any improvements can be made mention them and how this tutorial helped you if at all.

Here is the HOWTOS: http://autopsy.thetabox.org/HOWTO

It is in MOV format and can be viewed in Windows XP or Linux with mplayer's codecs packages.

For mplayer with mplayer codecs try this:

mplayer -vo x11 howto-rpmbuild.mov

I'll build an mplayer-codecs package and post it here shortly also.
