If not for FreeBSD, something is wrong in some #if conditions, no need to handle FreeBSD specially because HAVE_STRUCT_TM_TM_GMTOFF should be defined. FreeBSD is the last BSD remaining the conflict between ancient timezone function and standard timezone variable (already resolved in NetBSD, OpenBSD and DragonFly BSD ), but such condition is not only on FreeBSD.

With configure, builtin iconv is detected, but in build phase, iconv.h from libiconv is found. If you really want to use libiconv from ports for iconv(3), you can pass --with-libiconv-prefix=/usr/local to configure and libiconv from ports will be found. If you want to use builtin iconv, I have no idea except uninstall libiconv package, or temporary remove /usr/local/in...
