Perl 5.005 thru 5.8.5 probably can still run TTYtter, but they are not
tested with it. if you want to suppress this warning, specify -oldperl on
the command line, or put oldperl=1 in your .ttytterrc. bug patches will
still be accepted for older Perls; see the TTYtter home page for info.
for Perl 5.005, remember to also specify -seven.

your configuration requires using POSIX signalling (either Perl 5.14+ or
you specifically asked with -signals_use_posix). however, either you don't
have POSIX.pm, or it doesn't work.
TTYtter requires 'unsafe' Perl signals (which are of course for its
purposes perfectly safe). unfortunately, due to Perl bug 92246 5.14+ must
use POSIX.pm, or have the switch set before starting TTYtter. run one of
export PERL_SIGNALS=unsafe # sh, bash, ksh, etc.
setenv PERL_SIGNALS unsafe # csh, tcsh, etc.
and restart TTYtter, or use Perl 5.12 or earlier (without specifying
-signals_use_posix).
