Can't Update PHPBB (Manually)

I’ve tried to update my PHPBB forum from 3.0.2 to 3.0.7 and no matter what package I try (Auto Update - Changed Files - Full) I get some error with the install scripts.

If I just go to the install folder I get:
Parse error: syntax error, unexpected T_DOUBLE_ARROW, expecting ‘)’ in /home///language/en/install.php on line 288

If I try the update_database.php I get:
Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /home/*//install/database_update.php on line 1365

I’ve asked on the PHPBB forum, but they seem to not know. I have to think that there is something up with the PHP on Dreamhost. I’ve tried several packages, so I doubt it’s a case of file corruption. I’ve had similar problems with WP in the past.

What could be the deal? Is this something I can send in a support ticket for?
