[OS X TeX] Permission problems in texmf.local

[Michael S. Hanson]

	About two weeks ago I ran the latest i-Installer at the time to update 
my desktop TeX installation.  Today when I tried to use the Fourier 
math fonts (in a document that had compiled fine on this Mac prior to 
the update), I received the error:

!LaTeX Error: File 'fourier.sty' not found.

	This file is where I had installed it some time ago -- in texmf.local. 
  However, I no longer have permission to access it (yes, I am using an 
admin account):

% kpsewhich fourier
/usr/local/teTeX/share/texmf.local/tex/latex/fourier: Permission denied

	Turns out, a number of the directories under texmf.local have their 
execute bit turned off for group/others:

% ls -lF /usr/local/teTeX/share/texmf.local/
total 16
drwxr-xr-x   3 root  admin   102 14 Sep  2003 doc/
drwxr-xr-x   3 root  admin   102 15 Jul  2003 dvipdfm/
drwxr--r--   4 root  admin   136 14 Sep  2003 dvips/
drwxr-xr-x   3 root  admin   102 21 Jan  2003 etex/
drwxr--r--   6 root  admin   204 14 Sep  2003 fonts/
-rw-r--r--   1 root  admin  7923 30 Mar 14:29 ls-R
drwxr-xr-x   3 root  admin   102 21 Jan  2003 pdftex/
drwxr--r--   5 root  admin   170 18 Sep  2003 tex/
drwxr-xr-x  44 root  admin  1496 30 Mar 14:29 web2c/
drwxr-xr-x   3 root  admin   102 21 Jan  2003 xdvi/

which I suspect (I only know enough Unix to be dangerous (TM)) is why I 
cannot "see" the fourier.sty file (and presumably others).


Questions:

	1. Is it safe to execute 'sudo chmod -R go+x *' in 
/usr/local/teTeX/share/texmf.local/ ?  If not, what should I do 
instead?

	2. What happened?  On my PowerBook (not updated since October, the 
last time my desktop had been updated before the end of March), the 
permissions all appear correct -- or at least I encounter no errors 
when using fourier.sty.

	Thanks in advance for any assistance.
