lightsquid outdated readme

Hi,

I'm trying to install lightsquid on OpenBSD 6.7.

What i done :

---
rcctl enable slowcgi
rcctl enable httpd

httpd.conf looks like
server "default" {
listen on egress port www
root "/htdocs/lightsquid"
log error error.log
directory index "index.cgi"
fastcgi socket "/run/slowcgi.sock"
}

cd /var/www/htdocs
chmod -R 755 lightsquid
chown -R www.www lightsquid

rcctl start slowcgi
rcctl start httpd

---

When i try on a browser i get "500 Internal Server Error"
And /var/log/daemon => slowcgi[60466]: execve
/htdocs/squidanalyzer/lightsquid: Permission denied

Can you help me ? And is it possible for you to update the file
/usr/local/share/doc/pkg-readmes/lightsquid ?

Many thank's!
