Apparently, it was a bit more complex than that:

audit2allow -M privoxy -i /var/log/audit/audit.log
Generating type enforcment file: privoxy.te
Compiling policy
checkmodule -M -m -o privoxy.mod privoxy.te
semodule_package -o privoxy.pp -m privoxy.mod

******************** IMPORTANT ***********************

In order to load this newly created policy package into the kernel,
you are required to execute

semodule -i privoxy.pp


[root at alcibiades ~]# semodule -i privoxy.pp

The denial messages were different, but still no cigar:

type=AVC msg=audit(1145284191.527:141): avc:  denied  { recv_msg } for
saddr=209.233.191.3 src=8080 daddr=192.168.0.5 dest=37465 netif=eth1
scontext=system_u:system_r:privoxy_t:s0
tcontext=system_u:object_r:privoxy_t:s0 tclass=tcp_socket

I then repeated the audit2allow and semodule commands and this time it
works.

HOWEVER, after I posted the initial message, I realized that all I had
to do was bypass Privoxy for the library's domain in my browser
settings.  So perhaps it isn't really necessary to mess with the policy.
