[NTG-context] Help with ConTeXt Minimals and ppchtex

Hello, I've got a problem with the chemic-module and ConTeXt Minimals. My OS is Ubuntu 7.10, I installed the Minimals as it is described in http://wiki.contextgarden.net/ConTeXt_Minimals under "Quick Start". I got the error that is listed here: http://nopaste.ch/061d2c39cdda41c.html The user "mohbana" from the IRC directed me to the mailing-list, he already told me to rehash and do luatools --generate texmfstart texexec --make --all --luatex en texmfstart texexec --make --all --pdftex en texmfstart texexec --make --all --xetex en but nothing helped. I would be glad if you could help me, yours, Philipp.
