[racket-dev] Build failure on OS X

It looke like you have `-L/opt/local/lib' in your LDFLAGS
configuration. Do you also have `-I/opt/local/include' in CPPFLAGS?

You machine is probably like mine, where you have two installations of
libiconv, and this error happens when the C headers of one installation
get mixed with the lib of the other.
