I was able to get it to work using the same Ubuntu 9.04 (jaunty) configuration, using the apache2-mpm-prefork model. (Hooray for virtual machines!)

I added the snippet you provided to /etc/apache2/httpd.conf, which is ok since that file is included by /etc/apache2/apache2.conf. I fixed the one typo, changing "PerlOptions _ParseHeaders" to "PerlOptions +ParseHeaders".

Then I put the following "Hello World" program in the /var/www/perl directory, named hello.pl. I was surprised that I did not have to make it executable. 

#!/usr/bin/perl
print "Content-type: text/html\r\n\r\n";
print "<HTML>\n";
print "<HEAD><TITLE>Hello World!</TITLE></HEAD>\n";
print "<BODY>\n";
print "<H2>Hello World!</H2>\n";
print "</BODY>\n";
print "</HTML>\n";
exit (0);

And after stopping/starting the server, I got the expected output. I did do a full stop then start on the server. A restart will warn about the typo but not stop the server from executing. Perhaps this is your problem.

I didn't do anything special with permissions: 

root@jackalope 680# ls -ld /var /var/www
drwxr-xr-x 15 root root 4096 Dec 12 09:11 /var
drwxr-xr-x  3 root root 4096 Dec 12 09:41 /var/www
