[NTG-context] making format fails at "setinterfacevariable"

At work, in my minimal installation on OSX 10.4 PPC, making formats fails, whether I try first-setup, context or texexec: loading : Context Multilingual Macros / Initialization (/usr/local/ConTeXt/tex/texmf-context/tex/context/base/mult-def.tex (/usr/local/ConTeXt/tex/texmf-context/tex/context/base/mult-en.tex ! Undefined control sequence. l.5 \setinterfacevariable {Addition}{Addition} What's wrong? At home on OSX 10.5 Intel it works. Greetlings from Lake Constance!
