Strict refs

Jeg har en linje i /usr/local/lib/perl5/site_perl/5.005/Net/IRC/Connection.pm som ser sådan ud (linje 855):

_nick      => $ENV{IRCNICK} || eval { scalar getpwuid($>) }^M


Når filen eksekveres får jeg følgende fejl:

Can't use string ("LocalAddr") as a HASH ref while "strict refs" in use at
        /usr/local/lib/perl5/site_perl/5.005/Net/IRC/Connection.pm line 855 (#1)

    (F) Only hard references are allowed by "strict refs".  Symbolic references
    are disallowed.  See perlref.
