Some users have reported that Configure halts when testing for
the O_NONBLOCK symbol with a syntax error.  This is apparently a
sh error.  Rerunning Configure with ksh apparently fixes the
problem.  Try
       ksh Configure [your options]

POSIX threads should be supported by FreeBSD $osvers --
but your system is missing the shared libc_r.
(/sbin/ldconfig -r doesn't find any).

Consider using the latest STABLE release.
