Thanks.. I'll look into this.

For those who don't know, OS X 10.4 was the first OS X to run on  
Intel, so the OS X version MUST be at least 10.4 (Tiger). The version  
of the Intel Compiler is at last 9.1 as that was the first version to  
run (non-beta) on OS X.

I took out the IF(UNIX) thing and the libs are still trying to link  
against libm. I have no idea where it is coming from at this point.

According to the intel docs, as long as #include <mathimf.h> is  
somewhere in the includes, the intel compiler will use its own math  
library (by statically linking), obviating the need for libm.
   So where all would I start looking to remove the addition of libm  
into the link_libraries?

  I finally have my intel mini in an accessible location to the  
internet and I would be more than happy to setup a dash board for ITK  
(and vtk for that matter) that uses icc/icpc on OS X. I just need  
some hand holding to get it done.

I also tried to compile as static libs instead of shared and all the  
warnings about duplicate definitions went away until I started  
linking some of the itk apps, like itkTestDriver, then I get the  
following:
