Comment (by ryandesign):

 Replying to [comment:21 kencu]:
 > I don't completely understand how the variants are propagated -- maybe
 you can help me with that. For example, on Tiger, you first install
 {{{{apple-gcc-4.2 +bootstrap}}} and then once that is installed, you run
 {{{sudo port -v install apple-gcc-4.2}}} and it somehow reinstalls itself
 without the bootstrap variant, which surprised me. I thought port would
 see the previous +bootstrap variant enabled and would try to keep that
 variant enabled.

 Variant selections are preserved when you upgrade, not when you install.

 This apple-gcc42 +bootstrap variant situation isn't great either. There
 should be a separate apple-gcc42-bootstrap (sub)port instead.
