Comment:

 I think {{{libutil.h}}} and the dependency on {{{libutil.so}}} can be
 avoided using {{{posix_openpt}}} instead of {{{openpty}}}. The former is
 specified in POSIX.1-2001 and is available on FreeBSD, Linux, OSX and
 Solaris 10 according to Stevens and Rago, Advanced Programming in the UNIX
 Environment.

 I will work on a patch.
