 There is an option: "--enforce-variants".

 It only applies to upgrade. Not to install.

 It is useless. Watch:
 (NB: Sorry for double spacing. Neither <pre> nor <code> stop "line join".)

 Kleiman-ibook:~ michael$ sudo port install --enforce-variants  gtkglext
 +universal  gtk2 +universal openal +universal

 Error: install does not accept --enforce-variants

 Kleiman-ibook:~ michael$ sudo port upgrade --enforce-variants  gtkglext
 +universal  gtk2 +universal openal +universal

 Error: gtkglext is not installed

 Kleiman-ibook:~ michael$ port info gtkglext

 How does something like this happen? Well, I've installed a bunch of X
 stuff for my own use, so none of the things were installed as +universal.

 Now I need to create a universal .dmg for a program that uses X stuff --
 no one else doing development has a PPC mac anymore, and most developers
 are on linux.

 In general, Macports has a design flaw -- if package X exists, it is
 assumed to satisfy any dependencies that the requiring package has, even
 if those dependencies require a different set of options. There does not
 seem to be a "I need package X with option Y enforced" declaration. Nor is
 there anything like "the +universal option to me requires the +universal
 option to all my children".

 Note that in general, the required names won't be constant -- one program
 might take "+darwin9", and require "+darwin" on some children.
