MarketPress Plugin Won't Install

Hello,

Immediately after selecting to install the MarketPress plugin in a 'brand new' wordpress site (I actually dropped the dB and all files and re-installed WP clean), I get the following error:

Parse error: syntax error, unexpected T_FUNCTION in /home1/data10/public_html/duanesmith.com/73threads.com/wp-content/plugins/marketpress/includes/common/class-mp-installer.php on line 157

The MarketPress plugin isn't even active and this happens. The only way to make the site work once again is to actually delete the marketpress folder from within the plugin folder.

Can you help point me in the right direction?

Thanks,
