Commenting plug-in error: "Parse error: syntax error ..."

Hi everyone,
I'm installing Omeka on a new server. So far, things are going... pretty well. I've got the program running, and now it's time for fine-tuning with themes and plug-ins. Unfortunately, when I upload the Commenting plug-in to the appropriate folder, and then navigate in the /admin terminal to the 'plug ins' page, I get a blank page with the following:
Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in /home/fab/public_html/archives/plugins/Commenting/CommentingPlugin.php on line 182

Anyone have any advice?

Looks like T_PAAMAYIM_NEKUDOTAYIM is Hebrew for double-colon. Doesn't really help me, but interesting to know!

So, I replaced the double-colons with -> and now everything seems to be working. Strangely, this result makes me nervous.

Ahh....that's a syntax that works in PHP 5.3, but not in lower versions. Most of the time that change should be fine, but it'll be something for us to adjust for future releases.
