 Thank you very much for the pointer, but I'm afraid that it is not
 applicable to this case.  The patch for net/msend looks clean because
 msend already has codes for utmpx (calling get/setutxent instead of
 directly reading the utmp file when USE_UTMPX is defined).  The patch
 just defines USE_UTMPX and fixes incompatibility of a member name.
 
 The actual problem (or difficulty for me) is that mailagent is a Perl
 script and there seems no way to obtain utmpx data structure by a Perl
 script (maybe except writing a C module calling set/getutxent ?).
 utmp-era programs can read and parse utmp file directly, but utmpx
 file is not directly readable (the file format (futx?) is hidden
 inside libc and there seems no way to read it in a portable way).
 
 CPAN has User::Utmp module, but it is not in FreeBSD ports collection.
 I tried to build it by myself but failed on 9.x.  Also the author of
 mailagent seems to have a policy not to use any external modules.  So
 I was stucked and decided to call /usr/bin/who instead, because
 mailagent just needs users and tty names they are on.  mailagent uses
 them to decide which ttys to biff.  I don't use biff function, but at
 least I want it to work as expected.
 
 I have only a little knowledge about utmpx on FreeBSD 9.x so my
 understanding might be wrong.  If there is a clean way to access utmpx
 from a Perl script, I'd like to know.
