Comment (by jonesc@…):

 In ticket #36093 Angelo has reported that root now builds with gcc47, but
 at run time we get

 {{{
 Error Loading libTrackMathCoreDictdyld: lazy symbol binding failed: Symbol
 not found: ___emutls_get_address
   Referenced from: /opt/local/lib/libstdc++.6.dylib
   Expected in: /usr/lib/libSystem.B.dylib

 dyld: Symbol not found: ___emutls_get_address
   Referenced from: /opt/local/lib/libstdc++.6.dylib
   Expected in: /usr/lib/libSystem.B.dylib
 }}}

 Based on comment 52 above, I believe the installation used the binary
 tarballs for darwin 11, so I am wondering if there is a mis-match here if
 the user has a different /usr/lib/libSystem.B.dylib to that on the build
 bot ?

 Angelo, could you try reinstalling gcc47 and libstdcxx, forcing a build
 from source (port -s) ?
