[OS X TeX] Bibtopic

[Hélène Fernandez]

Hello,

I'd need to use bibtopic, but \usepackage{bibtopic} yields the 
following result :

LaTeX2e <2001/06/01>
Babel <v3.7h> and hyphenation patterns for american, british, french, 
german, n
german, italian, latin, spanish, nohyphenation, loaded.
(/usr/local/teTeX/share/texmf.tetex/tex/latex/base/book.cls
Document Class: book 2001/04/21 v1.4e Standard LaTeX document class
(/usr/local/teTeX/share/texmf.tetex/tex/latex/base/bk11.clo))
(/usr/local/teTeX/share/texmf.tetex/tex/latex/bibtopic/bibtopic.sty
(/usr/local/teTeX/share/texmf.tetex/tex/latex/base/ifthen.sty))
Runaway argument?
{\let \change at bibcite \relax \def \bibcite ####1####2{\global \ETC.
! File ended while scanning use of \@argdef.
<inserted text>
                 \par
l.10

That's even using absolutely no other package in the document.

I'm using G.Wierda's tetex tree and Oztex. Bibtopic was downloaded from 
CTAN  (don't know if I put it in the best place).

Help!
