Comment (by kencu):

 see this bit in the Portfile:
 {{{
 # clang++ produces broken boost libraries
 (https://trac.macports.org/ticket/31525)
 # If Apple's clang is used on 32-bit systems, it seems to silently ignore
 the '-march=i386' flag.
 # (https://trac.macports.org/ticket/38157)
 compiler.blacklist {clang < 421} *llvm-gcc-4.2 *gcc-4.0 gcc-3.3
 }}}

 probably more info in [ticket:31525]

 I'm not sure if I've ever built boost +universal on this system...
