This is because teTeX and TeXLive include different versions of the
xcolor package, called implicitly by beamer and defining (not in all
cases) the command \rowcolors:

- teTeX includes version 2.00 of 4 July 2004, and \rowcolors is
always defined.

- TeXLive-2007 includes version 2.11 of 21 January 2007, and
\rowcolors is defined only when the option [table] is specified,
apparently.

Hence, in order for beamerexample1.tex to typeset with TeXLive-2007,
you need to modify it to call the beamer package with option [table],
so that this option is passed on to xcolor.

I don't know whether there is a dedicated beamer mailing list (or a
bug report system somewhere), given I'm no beamer user myself, but if
there is then it could be appropriate to report the problem there.

Generally, if you're in a rush and don't have time to devote to such
compatibility problem (and have loads of disk space), you can install
teTeX using i-Installer (ignoring the warning about it being
deprecated). The TeX Distribution system pref panel which is
installed by MacTeX allows very easy switching between several
installed distributions. Using teTeX is not a viable strategy in the
long term, but it may help when you're in a work crisis and have more
pressing issues to deal with than TeX ones.

Hope this helps,
