You need to tell your system that it should look in /usr/texbin before 
/sw/bin. For this, you edit the file


(this is the default, if you don't have it, it could also be
~/.bash_login or ~/.profile). There is a line

   test -r /sw/bin/init.sh && . /sw/bin/init.sh

in this file. Add another line

   export PATH=/usr/texbin:$PATH

after the one with /sw/bin/init.sh.

Once you have done this and opened a new Terminal window, `which latex`
should give /usr/texbin/latex.
