I've developed (and attached) an eClass that follows the guidelines of http://www.ctan.org/installationadvice/ for single-user LaTeX installations - such as gentoo ebuild of teTeX. It takes care of ins/dtx files, as well as font files, documentation, style files, and scripts.
Created attachment 882 [details] eClass for LaTeX packages.
Checked into tree with a couple minor modifications at the top... Thanks for all your hard work :)
