For complex reasons we need to maintain availability of the default and 
older revtex (including the revtex 3.1!), so for revtex 4.1 we added a 
directory in texmf.local (but outside the usual search places) containing 
updated versions of:

   revtex, natbib, url

those being the latest versions taken striaght from CTAN - latest at the 
time we were asked for it.  Then for users to use it they need to set 
TEXINPUTS to include that directory before :: (meaning 'the usual path' of 
course), e.g. in our case (for historical reasons) we keep tex in 
/opt/tetex/ so the path to add is: /opt/tetex/share/texmf.local/revtex-4.1 
and users can set something like:

   export TEXINPUTS=/opt/tetex/share/texmf.local/revtex-4.1::

and similarly for BIBINPUTS/BSTINPUTS for bibtex etc.

It is a bit of pain for users, but I really don't like messing with the 
existing default installed revtex as I have too many nightmares about 
breaking existing documents doing something similar many years ago.
