As many have pointed out the error and alternatives, I want to point out that when debugging it's worth fully mining the error message.
For example, you posted the error and it said you didn't have an object on line 27 where the method print_name was being called. The object in question is $self->{lib} which should lead one naturally back to where $self->{lib} was set (or defined).
Looking at the definition of $self->{lib} and knowing it's likely messed up might have shed light on the error; Assigning a return value of a method instead of an object where it seems an object was wanted.

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).
