Why does Install/OMPI.pm "cp" all the sources to another
directory before building it?

  ...
  Evaluating: require MTT::Common::Copytree
  Evaluating: $ret = &MTT::Common::Copytree::PrepareForInstall(@args)
>> copytree copying to <scratch>/installs/XfxU/src
  Copying directory: <scratch>/sources/mpi_get__ompi-nightly-trunk/trunk
  Running command: rm -rf trunk
  Command complete, exit status: 0
  Running command: cp -r <scratch>/sources/mpi_get__ompi-nightly-trunk/trunk .
  ...

The above happens with or without --force. Wouldn't it be
more efficient to just have one set of sources and configure
using --prefix?
