I don't get any errors. If libHSPlasma shouldn't affect anything, is it possible I"ve got a confused Blender? (Ubuntu elderly repository version plus manually installed version entirely in one directory - which is the version with PyPRP)
The \Blender 2_49b\.blender\scripts directory has PyPRP. The "main" .blender directory (the one where \scripts is basically a redirect to \user\share\ doesn't. SHould I try dropping PyPRP in there?
What really mystifies me is that it worked. Once.
Honestly, you've got to solve more puzzles to make the writing tools behave than you do in the game!
I'm not quite sure what the heek blender's logic is for this, but copying the scripts from \kate\blender2_49b\.blender\scripts\PyPRP (where you'd EXPECT them to work running blender FROM that blender directory) to \kate\.blender\scripts\ worked.
I shall scratch my head in befuddlement, mutter dire things about taking over different installs, and get back to what I was actually doing
You may recall that upon installing Blender, you were given a couple of options, on where to put stuff. Apparently you chose the User paths (which may be the default now-a-days(?) -can't remember; I always pick the everything-in-the-main-install-directory option, myself).
On a positive note: with your type of setup, you could (I assume) effortlessly set up a second user account, with a different flavour of Blender prefs and goodies, such as the old import version of pyPRP, for easy access.
