That would be a possibility: that the developers omitted an essential framework or library from the link line. But the fact that it says the error is for architecture i386, when the default build_arch on Lion is x86_64, suggests instead that you are building this port universal, but that a dependency is not built universal.

geos compiles fine universal for me, on Snow Leopard with Xcode 3. Other problems were reported already when using llvm-gcc-4.2 or clang, as would happen with Xcode 4 and thus on Lion:

https://trac.macports.org/ticket/30309

I've resolved that by forcing the use of gcc-4.2. Has that helped?

Yes, the postgis developers don't seem very responsive; they didn't respond to our upstream ticket about the aforementioned problem three weeks ago either.
