Are you sure you have Xcode properly installed and some 3rd party stuff doesn't interfere? This is what you get on a "vanilla" OS X:

checking iconv.h usability... yes
checking iconv.h presence... yes

checking for iconv.h... yes
checking for iconv... in libiconv
checking whether iconv accepts "UTF-8", "latin1", "ASCII" and "UCS-*"... yes
checking for iconvlist... yes
checking for iconv... yes
checking for iconv declaration... 
         extern size_t iconv (iconv_t cd, char * *inbuf, size_t *inbytesleft, char * *outbuf, size_t *outbytesleft);

iconv is part of the OS, so unless you have macports/fink or alike messing with you it shoudl work out of the box ... Check your config.log - it should tell you what's hitting you ...

Cheers,
Simon
