Alan, That's interesting. I'd somewhat forgotten about this. I'll have a look at the Debian specific issues and see if I can get the pdf driver packaged up. By the way - and I've probably mentioned this before - I use pbuilder to building the Debian unstable packages on a Ubuntu stable machine. You can do the same with Debian stable. This works well and is much lighter weight than installing a virtual machine. Advantages are that you keep a stable platform, but can test with cutting edge. For packaging it has the added advantage that you start with a clean base system each time which makes checking build and runtime dependencies much easier. You might be interested in this for plplot or for other projects - time permitting of course!
