my script to install & update

[Thomas De Contes]

hi :-)


i've made a script to install & update, so that the user doesn't care  
about install or update, the script knows what it has to do
http://dl.free.fr/dzkNWz5qP


well, right now i install it on a new computer,
and it gives

+ port sync
Warning: No index(es) found! Have you synced your source indexes?

??
does not "port sync" sync what need to be synced ?

+ port -u upgrade outdated
Error: No ports matched the given expression
+ exit 1

it already happened that "port -u upgrade outdated" made this error,  
but not often
i don't know in which conditions it happens
i would like to keep "|| exit" because sometimes it doesn't success  
to upgrade
