IEEETrans on Mac OS X with texlive

While compiling a journal paper, I got the following error message "I couldn't open style file IEEEtran.bst"

The IEEETrans TeX distribution can be manullay installed by using the packages from CTAN [1] or  IEEE [2]. However since I use macports, I just had to;

1. sudo port install texlive-publishers
