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,  

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,
