This isn't really the right email list for this question. Try this
list instead (to which I have moved the discussion).

However, this likely has to do with privileges to execute your perl
script. In the last couple of days, the beginners-cgi list has
answered your question at least twice. Remember, the webserver
(typically) runs a different user than you, so it may not have the
rights to execute the script. Also, calling a perl program from a perl
CGI script is probably NOT the best way to accomplish the task you are
trying to accomplish. You should probably read up a bit on database
access from CGI scripts and try an example or two.
