Latest release or latest CVS versions?  Please specify the release 
version number or the approximate data of CVS checkout.

This is a known problem and has been fixed in the CVS versions of both. 
  A solution for the versions you have is to turn on VTK_USE_SYSTEM_PNG 
and VTK_USE_SYSTEM_TIFF.  Then point the CMake variables that ask for 
the include path and libraries for png and tiff at the ITK versions.
