The rpms in that dir are normally built from the tarball source using the <A HREF="http://checkinstall.izto.org/" TITLE="izto.org">CheckInstall</a izto.org> utility. There is absolutely no guarentee that these rpms are even real rpms. They could be porn (I wish!). I have these files up there for the purpose of making them availabel to me whether I'm home or at work or wandering the world. I used to only have them accessible to myself through scp but some people asked me to make them available. So I did.
