[Insight-developers] symbol referencing error in itkDynamicLoader.o

[Bill Hoffman]

The message is saying that the symbols are in /usr/lib/libdl.so.1, however,
that library has not been added to the link line.   Is this code using an
ITK makefile?  If so, it should automatically, get -ldl, if not, then
you need to add -ldl to your link line.
