I have a fully updated texlive 2010, it contains:

%% Project: kvoptions
%% Version: 2010/12/23 v3.10

(It is in the Oberdiek bundle)

Please verify that `kvoptions` is read from the TL tree and not somewhere else.
You may have an old version somewhere which is found instead of the TL version.

There should be a line:
/usr/local/texlive/2010/texmf-dist/tex/latex/oberdiek/kvoptions.sty
in the log file.

Texlive 2010 is still  available at:

http://tug.org/2010/tlnet-final

It should be possible to point Tex Live Utility there and get an update.
(If you never updated you TL installation expect a > 1GB download, just update oberdiek and see if that helps.)
