[CMake] error using cmake on 64-bit platform?

[Vicka Corey]

hi -- i have a recent cmake build (from last week) and i'm trying to use
it to build vtk on 64-bit centos4.

i am using "ccmake ." as the command, and i get errors starting with:

 CMake Error: Error in cmake code at
 /space/lyon/9/pubsw/build/VTK/jupiter/4.4/VTK/CMake/vtkLoadCMakeExtensions.cma
 ke:7:
 LOAD_COMMAND Attempt to load the library
 /space/lyon/9/pubsw/build/VTK/jupiter/4.4/VTK/CMake/libcmVTK_WRAP_TCL2.so
 failed.

the file is definitely there:

jupiter% file /space/lyon/9/pubsw/build/VTK/jupiter/4.4/VTK/CMake/libcmVTK_WRAP_TCL2.so
/space/lyon/9/pubsw/build/VTK/jupiter/4.4/VTK/CMake/libcmVTK_WRAP_TCL2.so: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), not stripped

i tried using CMAKE_BACKWARDS_COMPATIBILITY of 2.2 (the default) and also 2.0 
to no avail.  any ideas?

thanks,
