I'll second that. There is a really good chance that Apache is not giving
your script the same environment as the shell. And that is why can't find
Perl.

Here's a snippet about environment variables from the Apache documentation
on CGI:
Path information and environment

When you run a program from your command line, you have certain information
that is passed to the shell without you thinking about it. For example, you
have a PATH, which tells the shell where it can look for files that you
reference.

When a program runs through the web server as a CGI program, it may not
have the same PATH. Any programs that you invoke in your CGI program (like
sendmail, for example) will need to be specified by a full path, so that
the shell can find them when it attempts to execute your CGI program.

A common manifestation of this is the path to the script interpreter (often
perl) indicated in the first line of your CGI program, which will look
something like:

#!/usr/bin/perl

Make sure that this is in fact the path to the interpreter.

In addition, if your CGI program depends on other environment
variables<http://httpd.apache.org/docs/2.0/howto/cgi.html#env>,
you will need to assure that those variables are passed by Apache.
