No:
require $pathtool;
is exactly the same as
require "File::Path";
which fails. Your other attempt,
eval "require $pathtool";
evaluates the string, which then looks like
require File::Path;
which succeeds. Consider using the following code if you want a dynamic module loader:
sub require_package {
for (@_) {
(my $file = $_) =~ s-::|'-/-g;
require "$file.pm";
};
};
Other alternatives which I recommend against are UNIVERSAL::require and Module::Load because they both hide fatal errors from you, for example compilation errors in the required modules.
Maybe you might want Module::Pluggable for a plugin system.

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).
