I have encountered same problem some (big) time ago.
Evolution also refuses to work, but opera, telnet, netcat, etc works
just fine.

Looks like it was related to library changes, like:

Probably it is related to:
...
20070228:
        The name resolution/mapping functions addr2ascii(3) and
ascii2addr(3)
        were removed from FreeBSD's libc. These originally came from
INRIA
        IPv6. Nothing in FreeBSD ever used them. They may be regarded as
        deprecated in previous releases.
        The AF_LINK support for getnameinfo(3) was merged from NetBSD to
        replace it as a more portable (and re-entrant) API.
...
not sure, but anyway - rebuilding fix that problem.
