How to install a 32bit port on a amd64bit machine

[Prudhvi Krishna Surapaneni]

Hi,
 is there a way i can install a 32bit port on a amd64 bit machine.
Ex:
     rite now istanbul port only compiles on a i386 system. But, i need that
port badly so is there a way to install in on my amd64 box ?

 Thanks in advance
