What is the error message that you get?  This is expected to be working.

So shared libraries have to be built with -i_dynamic and executables
without it?

We would like ITK to build on anyone's machine without manually adding
these flags.  I'd like to setup the listfiles to automatically add the
needed flags when needed.  Once we've decided what they are, I'll add the
necessary code.
