FYI you don't select platform variants like +darwin or +darwin_10 manually; MacPorts selects them for you automatically if they're necessary.

"clean" should have been enough. "clean --all" also removes the distfiles, but there is no reason to do so unless you get a checksum mismatch error.

64-bit kernel is irrelevant; so long as you have a Core 2 (and not a Core) processor, you support 64-bit programs, and Snow Leopards builds such by default.

Of what architecture is /opt/local/lib/libz.dylib? "lipo -info" tells you.

For what architecture are you now trying to build? Look at the "-arch" flags in the debug output.

There is apparently a mismatch between these two in your case.
