Unless you have a pressing need, you should install all software on Ubuntu from a repository — either the official repos or a PPA. If your reason for building from source is to get a more recent version, hunt for a PPA that tracks the most recent version.
If you’re building from source in order to help with development, then you should find out from the Imagemagick folks just what is required to succesfully build it from source.
It might be that you need to specify some flag to. Oh, by the way, Red Hat and Ubuntu use different names for packages. So if yum complains about a missing package, it shouldn’t be surprising if apt-get imqge find a package by that name. You shouldn’t mix package managers on a system unless you have a really good reason to do so. Even then, try every other option first.

I only installed the first jpegsrc from source and reinstalled ImageMagick via apt-get and it worked too. But normally, building from source just needlessly complicates things.
Just search the Software Center or Synaptic. Or thi tab completion on apt-get to discover the command: By the way, I strongly suggest that you remove all previous attempts to install imagemagick before you try to install using my method. Otherwise, you might end up with conflicts.
