 * Install openssh with macports
  * time an scp some large-ish directory from a remote host
  * launch a linux VM on the same hardware
  * time the same scp
  * compare

 My results: openssh on the Mac is roughly half the speed of openssh on
 Linux.  Now:

  * install gcc43 and gcc_select with macports
  * gcc_select mp-gcc43
  * {{{port upgrade -f openssh}}}
  * run the timing test again

 My results: timing approximately identical to Linux.

 My conclusions: When MacPorts is installed, it should force-install and
 use a stock gcc.  Failing that, all the installation guides should be
 updated to note that you might want to do that before installing anything
 else.
