Seems that you got unlucky, yes.

This sounds like a bug to me. Presumably the default variants
should have matched, between "archive" and "unarchive"...

+darwin_8 isn't even a real variant but a platform variant,
and it should match between 10.4.11 and 10.4.11 you'd think ?


Can't seem to reproduce it, though. Trying the same gets me a:
DEBUG: No TGZ archive: /opt/local/var/macports/packages/darwin/i386/ 
glib2-2.18.3_0+darwin_8.i386.tgz

So it must be something else that causes +darwin_8 to disappear
on your iMac installation. It is supposed to predefined for you.
