I asked Vlad about this on IRC a while back, since I'd started
building on intel and cairo needs to be compatible with the (ppc only)
10.3.9 sdk, and I hit the same problem. He said that the moz build
system used magic to do it.... eventually I got cross compiling (but
not universal builds) much as you did above by following through the
moz process.

Mozilla's universal builds use lipo, because, afaik, you *need* to use
lipo if you're building for a different sdk on the two platforms.

In short, I don't think anyone is doing universal builds of cairo without lipo.
