Comment (by ryandesign@…):

 It failed to build on the Snow Leopard buildslave (which uses gcc-4.2; the
 newer buildslaves use clang):

 {{{
 mask_list.hpp:80: error: invalid pure specifier (only `= 0' is allowed)
 before ‘;’ token
 mask_list.hpp:80: error: initializer specified for non-virtual method
 ‘libdar::mask_list::my_char::my_char()’
 }}}

 I could reproduce this on Mavericks by changing the compiler to either
 macports-llvm-gcc-4.2 or apple-gcc-4.2:

 {{{
 sudo port install llvm-gcc42
 sudo port install dar configure.compiler=macports-llvm-gcc-4.2
 }}}

 {{{
 sudo port install apple-gcc42
 sudo port install dar configure.compiler=apple-gcc-4.2
 }}}

 In r115111 I changed the port to only use the clang compatibility patch
 when the compiler is clang, but a better patch that works regardless of
 compiler is needed.
