I don't know much about apache, but on my system (RedHat 6.1), httpd is
at '/usr/sbin/httpd'.  Since you installed it via RPM, 'rpm -ql apache'
should tell you what you need to know to find it.  Of course, if all
else fails you can 'find / -name httpd | less' and go for a short beer!

You're missing an end " in the second to last line, which ought to read:

$subject\n\n$body\n</pre>");

This missing quote is preventing the 'print end_html()' instruction from
being executed, and leading to an error.  You could help yourself with
this (a) by using the "-w" switch on the first line where you specify
the path to the perl interpreter and (b) by using a highlighting editor
-- my favorite is emacs. :-)

Not if all you want to do is CGI.  The whole point of CGI is that the
web server doesn't have to know anything about the program except that
it's executable and that it returns the right headers.  CGI programs can
be perl, compiled C, bash, or whatever.  The modules here (like
mod_perl) are for running an interpreter *inside* the server process --
much more efficient than CGI, but not quite as general.

Good luck, and keep your spirits up!
