I don't think readline links against iconv. What that error says to me is that GHC is failing to link against *any* iconv. I bet that it's because you have iconv installed via Macports without +universal. Try:
$ file /opt/local/lib/libiconv.a
It should say:
/opt/local/lib/libiconv.a: Mach-O universal binary with 2 architectures /opt/local/lib/libiconv.a (for architecture i386): current ar archive random library /opt/local/lib/libiconv.a (for architecture x86_64): current ar archive random library
If nothing else, I've learned about checking locations and architectures of libraries in this little adventure, so I had checked that prior to writing. I do in fact have the universal binary installed. What's more, both the macport and system versions are universal. I tried telling cabal to explicitly use each, separately, and it failed both times, though it gave me a different error when compiling against the system lib. (It complained about readline again, which is why I assumed readline had some dependency on iconv.) I'm going to try what Gwern recommended (using the darcs repository for lambdabot) before I continue down this route. Thanks for your persistence.
