  You really need to be more specific.  Are you sure you relaunched bash
after editing .bashrc?  Bash only reads the configuration file once, at
startup, so if you simply edited it you would have missed the change.
Then you should have an environment variable called TEXROOT; check that
"echo $TEXROOT" returns /opt/context or /opt/context/tex or something
like that.  If so, you should be able to make the formats ("texexec
--make --all" for Mark II, "context --make --all" for Mark IV).
