multiple error messages

I have a php5-error.log on all my wordpress installs that’s getting huge. Provider moved everything to new servers.

[29-Jul-2011 01:33:30] PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/local/lib/php/extensions/no-debug-non-zts-20060613/magickwand.so’ – /usr/local/lib/php/extensions/no-debug-non-zts-20060613/magickwand.so: cannot open shared object file: No such file or directory in Unknown on line 0

The following is what the hosting company replied regarding this.

magickwand.so is not installed on our new servers becasue it is outdated and can cause security problems. You can install this through the pear module installer in your cpanel. We don’t suggest this becasue it can open your site to hackers. We suggest contacting your developer and have them update your account to not use magickwand.so

Okay, I can add it according to them but I have also been a victim of hacking (like nasty f$&%ing me over hacking. Any other solutions? what I magickwand used for?
