kcalvelli,
Having a working perl on all servers is not sufficient. Are they all the same version of Perl compiled with the same options? Are there any modules that rely on system libraries that might not be installed such as Math::Pari? The point I am trying to make is that the "they" and "them" you are referring to are making your job a maintenance nightmare.

With that said, I believe local::lib and a reliable way to change directories to the location of the perl script should be a viable solution in many circumstances (needs to happen in a BEGIN block prior to the use of the local library.

• 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).
