No iconv() implementation found in C library or libiconv

[Xu Qiang <Qiang Xu fujixerox com>]

Hi, all: 

I downloaded glib 2.6.4 (src) and want to compile it. But I met this error in "./configure": 
---------------------------------------------
checking for iconv_open... no
checking for libiconv_open in -liconv... no
checking for iconv_open in -liconv... no
configure: error: *** No iconv() implementation found in C library or libiconv
---------------------------------------------

However, I found there is a header "iconv.h" in the path "/usr/include/sys" (should be part of glibc). 

Anyway, I downloaded libiconv-1.9.2.tar.gz and installed it successfully into /usr/local. And now i run with "./configure --with-libiconv=/usr/local", but still the same error. :(

I am compiling this on FreeBSD 5.3 (i386). 

Looking forward to help,

Regards,
