Right.  To make it *much* better, you should never build the source
tree in place -- that is, don't do this:

  cd .../plt/src
  ./configure
  make
  make install

Do this instead:

  cd .../plt/src
  mkdir build
  cd build
  ../configure
  make
  make install

This point is not specific to PLT -- it's generally healthier to do
this for any autoconf-based build.
