To check for a complete line just use a regex: 
if ($buf =~ s/(.*\n)//) {
    # line is in $1
    my $line = $1;
    ...process $line here...
}

Note that the s operator conveniently removes the first complete line from $buf as well as returns whether there was a complete line found or not.

btw, have you considered using the Net::IRC module? Have a look at this example: http://jk0.org/projects/perl-irc-bot/
