I joined the cairo list and reported the problem.  Below is what
transpired.

  I have built cairo-1.10 on Snow Leopard (10.6.4) w/o a problem, both
  x64 and i386 variants.  So this might be a problem with your version
  of Xcode.  I'd try to check on the Apple developer site if there's any
  updates/knwown issues to that.

I said that I had the latest, 3.1.4 and software update showed nothing
needed further updating.

  I think it could be a problem with the configuration being correct only for
  one of the two architectures (in particular it looks like it detects uint128_t,
  but it is probably not available on i386).

  You should be able to compile each variant independently (rerunning the
  configuration script) and then link them together to get an universal library.

  I don't know if this would be a valid option, but would confirm my
  suspects about what the problem is.

  Can you check if building the i386 and the x86_64 versions separately
  and later merging them works?
  A good reference on how to merge the two builds is here:

  Please report the technote to the macports guys (and/or crosspost
  me to them ;) ).
  From what you're saying it looks like they assume that the configure
  script will produce the same results for ppc32/ppc64/i386/x86_64.
  To me this looks like a very strong assumption.

  If they can point out what we should change to help them get a
  universal binary, we can try to fix it in cairo.

  Oh, I didn't use macports -- I've built from scratch with ./configure;
  make; make install; and it went just fine.
