To follow up on this, and perhaps for others: it turned out that the build was pulling include files from /usr/include but getting its libraries from /opt/local/lib. I solved it this once by setting CPPFLAGS:

export CPPFLAGS=-I/opt/local/include

... before running configure.

I'm puzzled, though, because I've never had this problem before, including another OS X machine (this one, running 10.6) where I have libiconv installed through macports as well, and where CPPFLAGS is also not set by default in my environment. This isn't high enough on my list to paw through configure and try to figure out how include paths are computed, so I'll just leave this as a "use it if you need it" item.

Hope this helps others,

John
