[Plugin: WP-Hyves] Cannot activate on 3.0.3

I get this error when I try to activate. It happens with at least one more plugin, but not all:

Parse error: parse error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /var/www/vhosts/…../wp-content/plugins/wp-hyves/wp-hyves.php on line 93
