php - Enabling phar on Dreamhost shared hosting?

So, i'm trying to use Silex on my dreamhost account and I'm getting an error

Fatal error: Class 'Phar' not found in blah blah blah...

when I try to include the Silex.phar file. When I look at phpinfo(), there isn't a section for Phar, even though everything I've seen claims that Phar support should be included by default in php 5.3.whatever, which is what i'm running under. Any Ideas?

Answer

Figured it out. If you add a directory at ~/.php/5.3/ and then put a file called phprc in it with the following line in it

extension=phar.so

then the phar extension gets loaded.
