I think Gerben was planning changes, because of a problem that I had 
reported and Martin Costabel confirmed/elucidated: /Library/teTeX was 
originally a symbolic link (symlink) to /usr/local/teTeX. This meant if 
you were connected to another Mac, or to a FireWire disk, for example, 
also containing Gerben's teTeX install, and you did anything (deleting, 
modifying content) to the symlink /Library/teTeX on that Mac or disk, 
then you were actually modifying /usr/local/teTeX on your Mac, not on 
the distant Mac or FireWire disk. In another context, Martin had in 
this way, by deleting a symlink in a FireWire disk, deleted a whole 
multi-gigabytes directory on his Mac.

Trying to be clearer, imagine you are browsing a disk or distant Mac 
named "Remote" from a Mac named "Local"; then the significance of the 
symlinks /Library/teTeX on the two volumes were:

Local/Library/teTeX  -> /usr/local/teTeX = Local/usr/local/teTeX
Remote/Library/teTeX -> /usr/local/teTeX = Local/usr/local/teTeX

Gerben was planning to change this so that:

Local/Library/teTeX  -> ../usr/local/teTeX = Local/usr/local/teTeX
Remote/Library/teTeX -> ../usr/local/teTeX = Remote/usr/local/teTeX

It may be Gerben has indeed made the change (I'm lagging a few gwTeX 
versions behind), and what you see is indeed a manifestation of it. By 
the way, I think

	sudo ln -s ../usr/local/teTex teTeX

should be

	sudo ln -s ../usr/local/teTeX teTeX

(capital X).

Hope this helps,
