BEGIN{($path = $0) =~ s[[\\/][^\\/]+$][];}
BEGIN{ use lib $path;}
use implies BEGIN, so that BEGIN should not be needed.
There is a simpler way: use lib do { ... }, shown in Re^2: Calculations before using lib;. Combined with the s///r syntax from newer perls, this can be collapsed to use lib do { $0=~s[[\\/][^\\/]+$][]r };.
Also note that $0 may not always contain an absolute path:
>cat tmp.pl
#!/usr/bin/perl
use strict;
use warnings;
print "$0\n";
>chmod +x tmp.pl
>perl tmp.pl
tmp.pl
>perl ./tmp.pl
./tmp.pl
>perl /tmp/tmp.pl
/tmp/tmp.pl
>./tmp.pl
./tmp.pl
>tmp.pl
./tmp.pl

Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
