making pdf of docs

Is there something wrong that makes it impossible to build the doc as a 
pdf?

I started a build 4 hours ago, and it has still not finished (stuck at
100% CPU on my old 800Mhz 1G RAM machine).

I know that openjade is very slow so for the first 3 hours I didn't worry.
Now I'm starting to think that it will never finish.
