\Q or quotemeta is indeed what you needed.

But your problem is not connected with hardcoded regexes vs. regexes in variables. As Samy_rio correctly pointed out, the problem comes from the fact that '.' has a special meaning in a regex which you don't want in your case. Therefore you need to escape it: either by putting a '\' in front of it - which works fine for the hardcoded case an is a bit more complicated for variables OR you use quotemeta resp. \Q which works in both cases.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
