( #3333=superdoc: print w/replies, xml ) Need Help??

If I have a perl module installed on a development machine and I want to temporarily run a different version of that module (for example, a copy of the module in a local repo), I can modify the $PERL5LIB in my my bash profile and insert the path to the 'lib' directory in the temporary version of the module to the beginning of $PERL5LIB and then reload bash. Then, to restore the original module, I remove the path to the temporary module form $PERL5LIB and restart bash.

This isn't too bad but just curious to know if others do the same thing or if there is some less hassle free way of doing this. Perhaps I should be using local::lib instead? Note that I'm using perlbrew so I'm not sure if local::lib is a viable option for me. Thanks.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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).
