The output you attached 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 you are now trying to build boost.

I'm guessing bzip2 and zlib are built for i386, since you set build_arch to i386 in macports.conf and I know they support changing build_arch because I've tested them myself, but that 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. So this should be filed as a bug in the boost port.
