latex, tex package install

figured out a good way to install tex packages for a non root user.

grab what you need from a tds.zip file from here:
http://www.ctan.org/tex-archive/install/macros/latex/contrib

then unzip it in, eg, ~/texmf/
then i think you need to set an env var like TEXMF or something, and maybe run texhash or something, or maybe you don't need to do any of that (should have posted this right after i did it!) but at least i know this is the file type to use and where to get them.

this might help:
