bison was at one point necessary for Amber on Ubuntu. There was a line that
bison would interpret correctly, but the amber-provided yacc would not. It
was actually you (Scott) that caught the cause of this issue, and Dave that
checked in the fix (back in the CVS days from the look of the message log).

Here's the thread: . (I
actually remembered this thread...)

Not sure what this information serves.

Bison still isn't a bad package to have installed, though. Ubuntu is far
more minimalistic than many other distributions out there (necessitated by
the ubuntu folks sticking to the 700 MB CD limit where everyone else is
using DVD images). bison, ssh, csh, etc. are all packages that the Ubuntu
folks decided aren't necessary for the average user, but easy enough to
install for the CL guru.

All the best,
