FYI, the default setup follows the conventions of debian packages. 
Multiple paraview versions can share the same installation prefix if one 
just renames the executables in the bin directory to have version numbers.

You don't need to change the CMakeLists.txt file to configure the 
install locations.  The default settings will not be used if you set the 
variables in the CMake cache.  This should do what you want:

cmake -DPV_INSTALL_BIN_DIR:PATH=/bin \
       -DPV_INSTALL_LIB_DIR:PATH=/lib \
       -DPV_INSTALL_DATA_DIR:PATH=/share \
       -DCMAKE_INSTALL_PREFIX:PATH=/opt/paraview/2.4.0 \
       ../paraview-2.4.0 &&
make &&
make install DESTDIR=/var/tmp/paraview

The tcl library itself tries to compute a bunch of paths in which to 
look for init.tcl.  I don't know why it selects these paths.
