[OS X TeX] Finally we are grown up

I forgot an important prerequisite:

If you have already Gerben's TeXLive installed then you should change  
the name of his TeXLive folder to something else like gwTeXLive, it  
is in

/usr/local/

The new tex installation would still succeed though, but the  
structure would be really awkward, because the tex folder "2005"  
would be contained in the TeXLive folder of Gerben's distribution. It  
is really unfortunate that Gerben appropriated the name texlive for  
his distribution, not respecting the default path of the TeXLive (TUG).
