Summary:                    Building VTK.
DCMAKE_BUILD_WITH_INSTALL_RPATH:BOOL=ON and python wrapper
Description: 
Homebrew builds all software packages in a <tempdir> and then moves it to, e.g.
/usr/local/Cellar/vtk/<version>/... and /usr/local/lib/vtk is a symlink to that
dir.

We use DCMAKE_INSTALL_NAME_DIR and DCMAKE_BUILD_WITH_INSTALL_RPATH:BOOL=ON to
get the final RPATH correctly written into the libs, even if we build in a
<tempdir>.

Then, just during the "make install", we add the <tempdir>/build/bin to
DYLD_LIBRARY_PATH and that used to work well (before), since the freshly built
libs can find each other.

Unfortunately, now we get the error:

make install
[...]

[ 95%] make[2]: *** [bin/vtkpython] Error 1
make[1]: *** [Wrapping/Python/CMakeFiles/vtkpython.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....

Obviously, some make target associated with python wrapping already expected the
a dylib at the target install location (where it is not yet).

Now to my before-mentioned, ugly work-a-round:
Is there a better way than to introduce a temporary symlink: 
/usr/local/Cellar/vtk/5.8.0/lib/vtk-5.8 --->  <tempdir>/build/bin ???
I put this symlink, then "make" then remove that symlink, then "make install".
Seems to work. Python can import vtk.
