How to adjust the $TEXMFCNF variable not to interfere with ConText?

[Karl Berry]

Hi Pablo - if you can give me a recipe for how to reproduce the
problems, starting with a vanilla install, along with more specifics
than "it doesn't work" (as far as TEXMFAUXTREES in the env goes), I can
look into it further. There's always a reason. But I can't guess all the
commands that you ran. I haven't been able to make the problems happen
so far. --best, karl.
