Can I install an older version of MacPorts to easily compile i386 only on Snow Leopard?

What issue is that?

You cannot run an earlier version of MacPorts. Ports are no longer  
compatible with older versions of MacPorts. Also, 1.8.0 is the first  
version of MacPorts that works at all on Snow Leopard. Also, 1.8.0 is  
the first version that knows about passing -arch flags. Prior versions  
did not pass anything and assume the compiler will do the right thing.  
On Snow Leopard, the compiler will build 64-bit by default so if you  
somehow managed to get MacPorts 1.7 to work on it, it would build 64- 
bit software for you, with no way to change it.

To build 32-bit only in MacPorts 1.8, set build_arch to i386 in  
macports.conf. If you encounter problems, please report them.

A better way to get wine on Snow Leopard is to build all of wine's  
dependencies with the +universal variant (which will build i386 and  
x86_64), then install wine (or, currently on Snow Leopard, you'll have  
to use wine-devel) (which will build i386 regardless of your  
build_arch because the wine software is not 64-bit ready at this time).

It may be tricky to identify which dependencies you need to rebuild.  
Once you identify them, you would run

sudo port upgrade --enforce-dependencies PORTNAME +universal

for each identified port.

I'm not sure what command would do this all for you automatically. If  
someone knows it, please let me know.
