Comment (by frederic.devernay@…):

 This is due to the new Boost.Log library relying on TR1 result_of
 protocol, which is unimplemented in GCC 4.2.
 This probably won't be fixed
 https://svn.boost.org/trac/boost/ticket/8769
 unless somebody wants to fix it
 https://svn.boost.org/trac/boost/ticket/8639 .

 Here's the homebrew pull request I got this information from
 https://github.com/mxcl/homebrew/pull/20947 .

 clang 3.3 is probably the most viable option, as it is for all ports which
 will break in the future because they are using C++11 features.

 Keeping the universal variant is an important issue, since the concerned
 OS versions may require it (universal only means something up to 10.6,
 after that all machines were 64-bits intel anyway).
