squirrelmail package in lenny

[Benjamin Vetter <vetter@plainpicture.de>]

Hi

I'm wondering why the squirrelmail package has a php4 -or- php5 
dependency http://packages.debian.org/en/lenny/squirrelmail
I updated from etch to lenny long time ago, but I still had etch's php4 
installed through this optional dependency, because lenny does not have 
any php4 packages (only php5).

Furthermore, there is no security support for etch anymore, so it would 
result in using a rather old php4 package without security support?

Best regards
