[OS X TeX] problem with context/m-ch-en.sty

[William Scott]

Hi Folks:

I am new to the list, and searched the archives for an answer to this  
question but did not find it...

Using the current tetex installed via fink, or any of the ones  
installed with ii2,  I am running into the following error when using  
this preamble:

\documentclass[10pt]{article}
\usepackage{geometry}
\usepackage{chemarr}
\usepackage{m-ch-en}


(/usr/local/teTeX/share/texmf.tetex/tex/latex/context/m-ch-en.sty
(/usr/local/teTeX/share/texmf.tetex/tex/latex/context/m-pictex.sty
(/usr/local/teTeX/share/texmf.tetex/tex/context/base/m-pictex.tex
(/usr/local/teTeX/share/texmf.tetex/tex/generic/pictex/prepictex.tex)
(/usr/local/teTeX/share/texmf.tetex/tex/generic/pictex/pictex.tex)
(/usr/local/teTeX/share/texmf.tetex/tex/generic/pictex/postpictex.tex)))
! No room for a new \dimen .
\ch at ck ...\else \errmessage {No room for a new #3}
                                                   \fi
l.352 \newdimen\!!widtha \newdimen\!!heighta
                                              \newdimen\!!deptha
?

This worked fine with tetex 2.x installed with fink, but upon upgrade  
to 3.0 it no longer works.  Installation of any of 2.x or 3.0 via ii2  
also yields the above error.

I'm not sure where to begin to fix this problem, but it has made it  
impossible to produce chemical formulas and symbols.

Many thanks in advance for any suggestions,
