It may be a moot point, but I think it would be advisable to move over to CGI.pm as opposed to cgi-lib.pl. The functionality is pretty much the same, and (I think) the query parameters are easier to access. Any programmer who might later look at your code will expect CGI.pm. All in all, I guess it all depends on whether or not you want to spend the time porting to CGI.pm.

As an interesting side note, Tom Christiansen wrote a little piece in 1996 about using CGI.pm instead of cgi-lib.pl. A lot of it doesn't really apply now, but it's somewhat amusing to read now.
