a lot of people are using Image::Magick. There's another one starting on the front page as I write. And my answer when you asked this question a couple of hours ago stills stands :)
If IM tools like convert and mogrify work from the command line, but Image::Magick fails oddly, then it's nearly always because the versions of Imagemagick and Perlmagick don't match. I often find myself in that situation after wresting with a reluctant installation for a while, and the answer is usually to go to the sources from which IM was compiled and install the version of PerlMagick that came with it.
