In general, no.  There may be some ports that you could cross-compile,
but that depends on the upstream software having support for cross
compilation (basically allowing "--target foo" into the compilation
flags.) Even if you fix that you're going to run into difficulties as
soon as you try and compile a port that depends on shared libraries from
another port.  I don't think there's any mechanism for installing 32-bit
shlibs into ${LOCALBASE}/lib32 from packages.

Oh, and making packages is potentially a mine field, as you need to
install the port in order to package it.

About the only way to cross-build ports is to set up a 32-bit jail on a
64-bit host.  I believe that is do-able, but I could be delusional.

	Cheers,
