Comment:

 The log shows that libgcc from gcc49 failed to bootstrap:

 {{{

 }}}

 libgcc has been updated to newer versions since then, and we have
 [https://packages.macports.org/libgcc/ packages built] for 10.6 and later,
 so I assume whatever problem existed when this ticket was filed is either
 resolved or is specific to your computer.
