update.php won't run with aggregator module in use

I tried to update from 6.6 to 6.7. Took the sites offline. Carefully replaced all the files, as always. Went to run update.php and got a blank page. The url it gets stuck on is

site.com/update.php?op=info

I know this can be a problem with the server not allocating enough memory to drupal to run the script. Adjusted php.ini to allow 64m. One site (of four) did update, but the other three are giving me this error on the same url above:

Parse error: syntax error, unexpected T_VARIABLE in /path/to/modules/aggregator/aggregator.install on line 242

I have seen this before but didn't want to take the time to figure out how to solve it again, so I deprecated the aggregator module to the 6.6 version, and that worked.

Just thought you should know.
