try this? 
sub errmsg {
    local $Carp::CarpLevel = 1;
    Carp::croak "$_[0]";
}

update: i understand this is a rather contentious 'feature'! some suggest +=1 instead, or consider Carp::Clan..
again: +=1 doesn't work as i expected on a local, use local $Carp::CarpLevel = $Carp::CarpLevel + 1; as shenme suggested below!
