&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Architectures ==&lt;br /&gt;
&lt;br /&gt;
Snow Leopard and newer builds binaries as 64-bit by default. If you need to build the libraries as 32-bit, use the following command to fetch with the right architecture in ports:&lt;br /&gt;
&lt;br /&gt;
   sudo port install pkgconfig cppunit +universal protobuf-cpp +universal unittest-cpp libmicrohttpd libusb +universal&lt;br /&gt;
&lt;br /&gt;
And then modify the build step:&lt;br /&gt;
&lt;br /&gt;
  export CPPFLAGS=&amp;quot;-arch i386&amp;quot; &lt;br /&gt;
  export LDFLAGS=&amp;quot; -arch i386&amp;quot;&lt;br /&gt;
  ./configure&lt;br /&gt;
  make&lt;br /&gt;
  make check&lt;br /&gt;
&lt;br /&gt;
== Mac OS X Version 10.4 ==&lt;br /&gt;
&lt;br /&gt;
If you're building for 10.4 you need to run configure and make with MACOSX_DEPLOYMENT_TARGET:&lt;br /&gt;
&lt;br /&gt;
  export MACOSX_DEPLOYMENT_TARGET=10.4&lt;br /&gt;
&lt;br /&gt;
otherwise you'll get errors in the form&lt;br /&gt;
&lt;br /&gt;
 /Developer/usr/bin/ld: multiple definitions of symbol _create  ../plugins/stageprofi/.libs/libolastageprofi.dylib(single module) definition of _create&lt;/div&gt;</summary>
