PHP Startup error with fileinfo.so

So i noticed that my error log was getting a bit huge

Its full of this error

[27-May-2010 10:27:10] 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

No idea what that relates to - any pointers? Im on shared hosting - is it possible they have removed something?

I suspect you tried to use the fileinfo library in some prior versions which is only available in PHP 5.3 only. Is this the case?
