I will put it in fedora-testing today along with fixes for your problem.

Thanks.  I just installed it but afterwards, I still see these when I
run "sudo ldconfig" with setenforce 0:

You can always modify selinux policy by executing

grep ldconfig /var/log/audit/audit.log | audit2allow -M myldconfig
semodule -i myldconfig.pp

Yes, it produces:

    module myldconfig 1.0;

    require {
	    type home_root_t;
	    type ldconfig_t;
	    class capability dac_override;
	    class dir search;
    }

    #============= ldconfig_t ==============
    allow ldconfig_t home_root_t:dir search;
    allow ldconfig_t self:capability dac_override;

I can't help but think that the AVCs are due to something I did
instead of ldconfig or its shipped policy.  Any thoughts?


No this is because you are running ldconfig on files in your homedir, and we have not seen this before. See if selinux-policy-2.6.4-38 fixes your problem
