Evo uses gethostbyname_r.  However, this function is not available on
FreeBSD, so Evo includes its own version.  THAT may be buggy.  Linux
_does_ have gethostbyname_r, and thus the internal Evo function is not
used.  You may want to poke around the code, and see if something
obviously wrong jumps out at you.
