Nope.
By *default* on unix, there is some version of perl in /usr/bin/perl. Generally a newer version of perl is a /usr/local/bin/perl or /home/zaz/my_perl. On windows, generally active state perl is installed at c:\perl\bin\perl , but cygwin installs perl at c:\cygwin\usr\bin\perl, which, if you are using cygwin's apache, you would call perl by /usr/bin/perl . If you use Oracle, you can use the oracle version of perl (not really recommended) at a path (similar to) /u01/oracle/some/version/export/bin/perl .
As far as development systems being different than production systems, in general, they almost are *always* different. Generally, older systems are used as development boxes, since they don't need the speed of production servers. (Also accept *slower* boxes, since there are times when you can't control the production environment, especially when you don't have root on the box.)
BTW. 300th post. :-)

• 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.
