Bochs is exiting with the following message:

it's particularly nasty because it's before thunderbirds, so quicksand just hangs;

i looked into this a while ago and it had something to do with the build process. libtool perhaps, or another tool involved in the chain, was failing to generate compile targets for a bunch of the modules. it works on unix*.andrew and on my current checkouts on my laptop, but not on a fresh checkout on laptop, and not on office machine.

i couldn't figure out last time how to properly generate those compile targets. i don't remember now exactly what they were.
