Lots of error message for missing fileinfo.so

Just noticed my error log was huge, with lots and lots of error messages over the last few days that all look like this:

[08-May-2010 14:10:06] PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/local/lib/php/extensions/no-debug-non-zts-20060613/fileinfo.so’ - /usr/local/lib/php/extensions/no-debug-non-zts-20060613/fileinfo.so: cannot open shared object file: No such file or directory in Unknown on line 0

Any thoughts?

(I’m running latest version 0.6.1)

Piwik doesn’t use the fileinfo extension directly, and looking at Zend Framework, it checks if the fileinfo extension is available (or functions exist).
