each of them contains say pdftex but those are different

-rwxr-xr-x  1 root  wheel  2850996 Jun 16 19:11 universal-darwin/pdftex

on the other hand on 64-bit machine

%ls -l /usr/texbin/pdftex returns

--rwxr-xr-x  1 root  wheel  1572864 Jun 16 19:19 /usr/texbin/pdftex

and on 32-bit it returns

-rwxr-xr-x  1 root  wheel  2850996 Jun 16 19:11 /usr/texbin/pdftex

%which pdftex

returns /usr/texbin/pdftex

Actually /usr/texbin is a symlink to

lrwxr-xr-x  1 root  wheel  63 Jun 12 13:34 /usr/texbin ->

which in turn is a symlink to one of those


(depending on architecture)

There is a control panel in System Preferences where one can
select/change which path is used and on 32-bin machines only
/usr/local/texlive/2010/bin/universal-darwin could be chosen

Sio, in principle one can select a directory containing tex
executables and remove the other one - assuming that tlmgr (or TeXLive
utility which is MacOSX frontend for tlmgr) would not complain too

But this is only less than 150 MB for universal-darwin and less than
100MB for x86_64-darwin.
