One user reported that some recipes failed due to the copying of dirs.
I have hence updated the pkg framework to add a customized version (I
couldn't use dircp since it is, at least on 9front, a rc script; so I
ended up using tar).
You can update simply by updating the recipe to...@pkg.sh (that will
path the pkg library).
p...@tex.sh and bea...@latex.sh have been updated (you can retrieve
them individually or on bulk with r...@pkg.sh).
The bad news is that GhostScript is too old and, for beamer, it can't
translate the PostScript in PDF (it can't even display the
PostScript).
As said before, I can't do anything about that on the kerTeX side. For
this to work, GhostScript has to be updated. Not a small task (and
this is a reason why, I want to be able to have images without
requiring a PostScript interpreter).
