docbook: TeX capacity exceeded, sorry [pool size=10195]

[Gus <gusl@cse.unsw.edu.au>]

whenever i try:
sgmltools -v -b dvi file.sgml

i get:
[snip]
(/usr/share/texmf/tex/jadetex/base/isoents.tex
File: isoents.tex

! TeX capacity exceeded, sorry [pool size=10195].

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

in /tmp/@*.log


if it matters, i'm using:
sgmltools-2 2.0.2-2, docbook 3.1-0.2, docbook-stylesheets 1.40-1
and <!DOCTYPE article PUBLIC "-//Davenport//DTD DocBook V2.4.1//EN">


i don't know anything about sgml/docbook, and not enough about tex to
fix this one.. is this just me? or is no-one else able to produce
docbook output through jadetex?


if anyone knows a quick fix, i'd appreciate it - since i'd like to use
docbook for an essay i have due, just for a laugh (usually i use TeX)

(i don't know whether to file a bug against tetex or jadetex, hence my
post here)
