 Yes. The 10.7–10.10 builds ran and all failed due to:

 {{{
 absl/debugging/internal/examine_stack.cc:58:34: error: use of undeclared
 identifier 'MAP_ANONYMOUS'
                    MAP_PRIVATE | MAP_ANONYMOUS, -1, 0);
                                  ^
 1 error generated.
 }}}

 so that's a simple fix of:

 {{{#!c
 #ifndef MAP_ANONYMOUS
 #define MAP_ANONYMOUS MAP_ANON
 #endif
 }}}

 Or the legacysupport portgroup can be included which includes that fix.

 I'm not sure why the build succeeded on 10.6.
