[NTG-context] Failure to Install minimals on iBook G3

Hello, I tried in vain to install the minimals on an old (2003) but still functional iBook G3, running under OSX 10.4.11. After having received some 4MB, I get the message: "dyld: incompatible cpu-subtype" plus a reference to line 103 of first-setup.sh. Does anybody on this list know what could be done about this. Btw, this iBook can handle TeX and ConTeXt. I installed MacTeX 2009 and everything works. But I would prefer the minimals. Thanks in advance. Robert Blackstone
