Universal builds?

[Holger Rapp]

Hi,

since i have not found a forum/FAQ entry or something similar on the  
(miniscule) homepage, i post my question on the user list, hopefully  
someone can help me here.

I have a Macbook and i'm trying to get my ports stuff installed  
universal for cross compiling (or rather building fat binaries for  
other systems, so i need universal libs). But darwinport seems to be  
mocking at me:

$ port variants libsdl_gfx-framework
libsdl_gfx-framework has the variants:
         universal
         darwin_8
         darwin_6
$ sudo port uninstall libsdl_gfx-framework
--->  Deactivating libsdl_gfx-framework 2.0.13_0+darwin_8
--->  Uninstalling libsdl_gfx-framework 2.0.13_0+darwin_8
localhost:/opt/local/etc/ports sirver$ sudo port install libsdl_gfx- 
framework +universal
--->  Fetching libsdl_gfx-framework
--->  Verifying checksum(s) for libsdl_gfx-framework

--->  Activating libsdl_gfx-framework 2.0.13_0+darwin_8

hu? why wasn't the universal variant build and installed, rather the  
darwin_8? I couldn't find any documentation, i'd really like to know  
what i'm doing wrong?
(this happens with all ports btw, not just this random example picked)

thanks for your help
