[OS X TeX] teTeX still on my path

It depends on your shell. Using "Mac OS X Tiger in a Nutshell", and  
the respective man pages:

- For bash:

/etc/profile		Executed automatically at login
~/.bash_profile		Executed automatically at login
/etc/bashrc		Executed automatically at shell startup
~/.bashrc		Executed automatically at shell startup

There seems to be also two alternative names for ~/.bash_profile, I'm  
not quite sure what the difference is:

~/.bash_login
~/.profile

 From the Invocation section of the bash man page:

- For tcsh:

/etc/csh.cshrc		Executed at each instance of shell startup
~/.cshrc		Executed at each instance of shell startup
/etc/csh.login		Executed by login shell after /etc/csh.cshrc at login
~/.login		Executed by login shell after ~/.cshrc at login
~/.cshdirs		Executed by login shell after ~/.login

 From the Description section, "Startup and shutdown" subsection, of  
the tcsh man page:

Thus there seems to be a difference in the initialization procedures  
for bash and tcsh: if I interpreted the above correctly, for tcsh the  
effect of csh.cshrc and csh.login is cumulative, with csh.cshrc being  
read for a non-login shell (as in X11) and both csh.cshrc and  
csh.login for a login shell (as in Terminal), while for bash the  
effect of profile and bashrc is mutually exclusive, with bashrc being  
read for a non-login shell and profile for a login shell.

Somewhere in one of these files, a reference to teTeX must be hiding  
(or in a ~/.MacOSX/environment.plist, though that shouldn't affect  
Terminal, I think).
