Universal building is an experimental feature that has been the  
subject of heated discussion here and might or might not be included  
in future releases. It is currently only available in the trunk  
(development) branch of MacPorts.

The reason why you can see it when you run port variants is that  
"port variants" refers to the PortIndex file which is generated  
automatically on a system equipped with the trunk (development)  
branch of MacPorts and therefore which knows about universal builds,  
while your installation does not know about them and simply ignores  
this option.
