Comment(by aguynamedryan+macports@…):

 Replying to [comment:6 sjd4@…]:

 From your config.log:

 > ld: warning: ignoring file /opt/local/lib/libusb.dylib, file was built
 for unsupported file format which is not the architecture being linked
 (i386)

 There's yer problem!

 I think we're back to the whole "+universal" thing being a problem, but to
 be honest, I haven't grokked what is going one with architectures and how
 MacPorts works with them.

 When I ran into the problem when I switched from PPC to x86, I just
 trashed my whole /opt/local directory and reinstalled MacPorts fresh and
 built without universal.  Did the same thing when I migrated to Snow
 Leopard.  There is probably a better solution, but I don't know what it
 is.  Maybe someone else can jump into this discussion and give you better
 advice.
