st: changing adopath and profile.do with mac OSX

[Nirali Shah <nmshah@jhsph.edu>]

Hi,
I am using Stata 9 with my new Mac.  I want to permanently change  
where new .ado files are downloaded and stored, and to have a  
profile.do start each time I start Stata.

Currently, when I type -sysdir-, I see:
STATA:  /Applications/Stata/
 UPDATES:  /Applications/Stata/ado/updates/
    BASE:  /Applications/Stata/ado/base/
    SITE:  /Applications/Stata/ado/site/
    PLUS:  ~/ado/plus/
PERSONAL:  ~/ado/personal/
OLDPLACE:  ~/ado/

I can change the paths for PLUS and PERSONAL using:
sysdir set PLUS "/Applications/Stata/ado/plus/" and
sysdir set PERSONAL "/Applications/Stata/ado/personal/", but when I  
restart Stata, these directories revert to that above.  How do I make  
my directory change permanent?

In a related question, I thought I could create a do file which would  
run automatically when I start Stata.  I saved it in "/Library/ 
Application Support/Stata", but this does not seem to work either.

Any assistance for a new Mac and statalist user is appreciated.
