How about storing each line in a temporary variable, removing periods from that and then matching against the resulting string? e.g.

@matches=( qr/match1/,
           qr/match2/, ...);
open ($file,"<","/path/to/file") or die ("Horribly");

while (<$file>) {
  $temp=$_;
  $temp=~s/\.//g;
  for my $match (@matches) {
    if ($temp =~m/$match/) {
      do_something();
    }
  }
}

If you're only going to match against one value you're probably better off adjusting that value (e.g.

join(".?",(split(//,$match)))

), but if you have multiple matches(and possibly multiple ignorable characters) the first suggestion should work well for you.
