Remaining single-line change from patch #102409: to install shared modules,

   run setup.py with the --install-platlib flag so you can override
   'prefix' when running make (e.g. make prefix=/tmp/python/usr/local install)

Instead of using mkdir to create directories, use install -d (mkdir -p
   apparently isn't portable)

Emacs make-mode reported line 371 as suspicious; removed the whitespace from
   that line.
