Building rpms from tarballs

[alanr stateind com]

I read the earlier messages about building RPMs from tar-balls and decided to give it a try with gnome-core-1.0.9.tar.gz which I had downloaded a little while back. Anyway, I executed `rpm -ta gnome-core-1.0.9.tart.gz` and waited for a very long time. When it was all over, I found the source tree under /usr/src/redhat/BUILD/gnome-core-1.0.9 and and rpm labelled gnome-core-1.0.9-4.i386.rpm in /tmp. There was no *-devel-* to be found. Also, when I tried to execute rpm -Uvh gnome-core-1.0.9-4.i386.rpm, it said simply that it could not install it like this....

error: gnome-core-1.0.9-4.i386.rpm cannot be installed

During the rpm building, there were no obvious errors and it seemed to end peacefully enough. However, since this is the first time I've tried it, I don't know what it should say. 

I would like to suggest that the procedure from converting gnome tar-balls to RPMs be added to the FAQ. (I looked for it and didn't find it. Did I miss it?)
