The posting guide does ask people to read the documentation, and this is 
documented in the appropriate manual.

This is not intended to work: it is documented that LANGUAGE should be set 
outside the process.  Does no one read the manuals?  R-admin says

   `Note that you should not expect to be able to change the language once
    R is running ...'

It is phrased that way because it _sometimes_ will work on _some_ OSes and 
on _some_ versions of gettext.
