[vtkusers] unable to build vtk

[Antonio Coralles]

I'm using gentoo linux with gcc-3.3.5 and cmake 2.0.5 .

When i enter ccmake in my VTK directory, which contains the VTK-4.2 
release, and then hit c [for configure] i get the following error:

 CMake Error: Error in cmake code at
 /mnt/saddam/downloads/VTK/CMake/vtkLoadCMakeExtensions.cmake:7:
 LOAD_COMMAND Attempt to load the library 
/mnt/saddam/downloads/VTK/CMake/libcmVTK_WRAP_TCL2.so failed. Additional 
error
 info is:
 /mnt/saddam/downloads/VTK/CMake/libcmVTK_WRAP_TCL2.so: failed to map 
segment from shared object: Operation not permitted

 CMake Error: Error in cmake code at
 /mnt/saddam/downloads/VTK/CMake/vtkLoadCMakeExtensions.cmake:17:
 A command failed during the invocation of macro 
"VTK_LOAD_SINGLE_CMAKE_EXTENSION".

 Loading VTK command VTK_WRAP_TCL2 - failed

Is there a way to circumvent this problem ?

Thanks,
                Antonio
