This looks like an installation problem, since the linker is failing
to find symbols in the library.  Are you sure the library is valid?

The syntax errors in the __imagemagick__.cc file can't be caused by
the library problem though, so there is some other problem.

It's somewhat hard to tell given the information you provided.  What
kind of system is this?  How was Octave installed?  What commands did
you use to configure and build Octave Forge?

If you think you've found a bug in Octave or Octave Forge, please
submit a complete bug report.  Please read

provide to enable someone to help fix the problem.
