I'm sending this reply to the macports-users list, where any further discussion should occur.

Users are not meant to specify configure options on the command line, and doing so in the way you're trying will have no effect. Ports are meant to install correctly without the need to specify additional options.

How did you compile your qt libs to be 32-bit? The approved way to change the architecture of port compilation is to set build_arch in macports.conf. But since this is a new option, not all ports support this.
