Problem with ConTeXt installation

[Jeremy Johnson <jazz_johnson@verizon.net>]

I'm having problems starting ConTeXt with texexec
on my Gentoo system.

I've installed ConTeXt using the MikTeX Package Manager:
"for p in `mpm --list|grep context | tr -s [:space:] | cut -d ' ' -f 4`; do 
mpm --install=$p; done" 
followed by a "texhash" and an "updmap" for good measure,
and I've upgraded to the latest tetex-3.0_p1-r3 in Gentoo's portage.


I've also followed the guide:
http://wiki.contextgarden.net/Linux_Installation#Updating_Gentoo_Linux

and modified /etc/texmf/fmtutil.d/00fmtutil.cnf
by adding a '*' where indicated in the above referenced wiki.
followed by texmf-update.


BUT:
$ texexec --version

And if I try to process some contex file:

$ texexec test.tex
