Comment (by jalmar@…):

 I'm experiencing the same problem with MacPorts version 2.1.3 on Mac OS x
 10.8.3 when I try to install the InsightToolkit using the command
 {{{
 sudo port install insighttoolkit -doc -python25 +shared
 }}}

 The probleem seemed to be related to the fact Clang rejects a certain kind
 of construction detailed on the following webpage

 http://clang.llvm.org/compatibility.html#dep_lookup_bases

 What the webpage tells you is that the statement

 {{{
 return equal( this->data_block(), rhs.data_block() );
 }}}

 on line 657 of the file
 InsightToolkit-3.16/Utilities/vxl/core/vnl/vnl_matrix_fixed_ref.h is not a
 legal construction and should be changed to

 {{{
 return this->equal( this->data_block(), rhs.data_block() );
 }}}

 Notice the 'this->' in front of the the call to equal; from what I
 understand this is essential to refer base class of the derived class.

 There are a few more places where you have to change this illegal
 construction.


 The same problem exists in the file
 InsightToolkit-3.16/Code/Common/itkParametricPath.txx
 On line 46 and line 67 (twice! [2x]) you have to change the calls to
 'Evaluate(...)' into 'this->Evaluate(...)'

 There is another bug as well in the file
 InsightToolkit-3.16/Code/Common/itkKLMSegmentationBorder.h
 On line 84, 88, 103, 104, and 109 you have to change the statements with
 'rhs.m_Pointer...' into 'rhs->m_Pointer...' (Notice that the dot changes
 into the arrow)

 After that, I could build and install the InsightToolkit using the command

 {{{
 sudo port install insighttoolkit -doc -python25 +shared
 }}}

 without any further problems.

 Note sure if this helps any of you. Sorry, I don't know how to create
 patches, so you'll have to modify the source code yourself. Or maybe
 someone else can verify these fixes and patch the files for you. I believe
 they already fixed these particular problems in release 3.20 (see webpage
 https://itk.icts.uiowa.edu/fisheye/changelog/ITK?cs=68d1a8a60bd919e709e568c9e12477d2f632368a)
