Comment (by kencu):

 I see it built fine on 10.6 i386 using gcc-4.2 and the system assembler
 there.

 This block of the Portfile should ensure that no macports-clang compiler
 is used to build it:
 {{{
 if {${os.platform} eq "darwin" && ${os.major} < 11} {
     # Doesn't actually use C++, and having the stdlib set to libc++
     # on 10.6 causes a macports-clang compiler to be chosen.
     configure.cxx_stdlib
 }
 }}}

 Can you think of some reason that a clang compiler is being called in?
 That would appear to be what we need to fix on 10.5 i386 (which - AFAICT -
 should not be calling a clang compiler for this build in the first place).
