What steps will reproduce the problem? 1. Build ITK 3.20.1 and install it in /usr/local/. 2. Acquire CSWIG from macports (installed in /opt/local/) 3. Download wrapitk030 from wrapitk google site and attempt to build.

What is the expected output? What do you see instead? Should build with no issues if I have given the appropriate ITK_DIR in the CMake step. I get a problem with VXL. Please help! ...

What version of the product are you using? On what operating system? I have a 64 bit OS Lion and am trying to install wrapITK 0.3.0.

Please provide any additional information below.

Another piece of information - I am trying to bind wrapITK with python2.7.

ps: It seems to be the same unresolved issue as issue 37 - wrapitk build problems with python 2.7 on ubuntu.
