Here's what I've done in an attempt to resolve the AVCs so far on my
own system:
I have a directory that contains shared libraries that I want ldconfig
to know about. It and the files in it originally had this selinux
context:
user_u:object_r:user_home_t
I changed that to:
system_u:object_r:lib_t
using this command:
sudo chcon -R system_u:object_r:lib_t /home/depot/collections/tora-1.3.21/lib
This eliminated all but one of my failures in selinux. (Some time
ago, I changed the context of my $ORACLE_HOME/lib directory to
eliminate similar errors.) But I still see this:
type=AVC msg=audit(1186928212.253:1139): avc: denied { dac_override } for pid=5782 comm="ldconfig" capability=1 scontext=user_u:system_r:ldconfig_t:s0 tcontext=user_u:system_r:ldconfig_t:s0 tclass=capability

I believe these failures are an error in the shipped policy for
ldconfig. But I'm not sure. My reasoning is that ldconfig should be
able to search and/or read the root directory. I believe that both of
those failures are happening in a stat64() system call.
At this point, I don't know what to do about this. I see that Daniel
Walsh recommends trying selinux-policy-2.6.4-35.fc7 in bug #248703,
but I only see -33.fc7 in updates-testing. I wonder where I could get
the newer package?
