[Paraview] libQtHelp.so.4 error

[Utkarsh Ayachit]

Looks like "/usr/local/lib" is not a default path where your CentOS
looks for loading libs. The ParaView from the binary dir works since
it uses rpaths for all libs and it has the rpath for the Qt libs too.
That gets removed on install and hence the issue. Try googling around,
there must be a way to extend your default lib search path.
