You probably need to install the Jasper delegate library to use JP2000 images, then reinstall IM

You can tell what delegates you have installed by running

convert -list configure

and looking for the line starting with DELEGATES

see http://www.imagemagick.org/download/delegates/ (or find a more current version)

Do as it says, recompile Jasper with the -fPIC option on the compile command line.
