[MySQL4] Install difficulties

[Marco Battistella]

This might or might not be related to the problems occurring with the  
installation of mysql5 .
I installed mysql4 through macports  ($ port install mysql4 +server)
mysql would not start (from the command line).
Looking at the mysql error log i realized that there was a problem  
with writing permission to the directory '/opt/local/var/db/mysql'
I changed the owner of that directory from root to mysql and that  
fixed the issue.
I'm not sure if I had done something wrong causing this issue in the  
first place.
Hopefully this might help someone encountering a similar problem.
take care.
