okay, it looks like we're in need of a number of policy changes to
permit privoxy_t to do its job.

first set permissive mode

setenforce 0

then...
are you running auditd?
audit2allow -i /var/log/audit/audit.log (if you are)
audit2allow -i /var/log/messages (if you aren't)

it will tell you what you have to permit privoxy_t to do before it can
bind to port 8080. I have a feeling it is going to need a few changes to
the reference policy

much of this may be best posted to fedora-selinux-list where the SELinux
bigwigs hang out. They are far more expert on this than I
