[Yhc] At risk of being Noob

Hi, so I was trying those first trivial changes to move from PackedString to String, but one of the tests failed. I wanted to look at exactly what happened, so I tried running YHC directly but I got yhc: /home/wchogg/yhc/inst/bin/lib/yhc/packages: getDirectoryContents: does not exist (No such file or directory) as an error, which I presume is because I hadn't set YHC_PACKAGE_PATH. Except that all it says on the wiki about where to point it is that there should be an example. So what exactly do I need to do? Cheers, Creighton
