Upgrading from 2009 to 2010 is not possible. The bugs and updates page says the following:
It is not possible to upgrade from TL 2009 to TL 2010, so install the new release in a new directory (as is done by default). install-tl may offer to import options (not packages) from a previous release, but results are not guaranteed.

put the
.../texlive/bin/../
to your path and everything will be fine. A good idea is to create a filezzz-texlive.sh
in/etc/profile.d/
:replace 2010 with your current texlive year or change the whole path if you have another location of texlive.
