 {{{
 Machine:                MacBook Pro, 15"
                         MacBookPro10,1
 Processor Name:         Intel Core i7
 Number of Processors:   1
 Total Number of Cores:  4
 OS Version:             10.8.5
 Xcode verson:           5.1
 MacPorts version:       2.4.1

 There is a fix at least for the above machine: one should cause the
 build system to use 'macports-gcc-6' instead of the default compiler.
 One way to do so (maybe not the best) is do replace the original
 Portfile line

 compiler.blacklist  {gcc-4.0 < 5493}

 with the lines

 compiler.blacklist  {gcc-4.0 < 5493}

 compiler.whitelist  macports-gcc-6

 }}}
