New description:

 I tried to install a pure 32-bit version on snow leopard but failed since
 boost does not support the build_arch since boost. To verify this bug do
 the following:

   1 install macports pkg
   1 edit etc/macports/macports.conf and activate "build_arch i386"
   1 sudo port install boost

 The (attached) errot output says:

 {{{
 ld: warning: in /opt/local/lib/libbz2.dylib, file is not of required
 architecture
 ld: warning: in /opt/local/lib/libz.dylib, file is not of required
 architecture
 }}}

 So the bzip2 and zlib ports are not installed for the same architecture as
 that for which the system tries to build boost.

 guessed reason: bzip2 and zlib are built for i386, since build_arch is set
 to i386 in macports.conf and they suport build_arch. boost does not
 support changing build_arch and is therefore still trying to build for
 x86_64. A quick glance in the portfile shows that it doesn't use the
 standard configure phase (which is how ports automatically acquire support
 for changing build_arch) and searching the portfile for "arch" doesn't
 show any code that would cause the port to respect build_arch.
