It looks like iscsi-initiator-utils package in fedora is built using
shared libiscsi which appears to be package-specific, e.g.
http://www.rpmseek.com/rpm/iscsi-initiator-utils-6.2.0.870-13.fc13.x86_64.html?hl=com&cx=0:-:0:8107228:0:0:0:

Files:
/sbin/iscsi-iname
/sbin/iscsiadm
/sbin/iscsid
/sbin/iscsistart
/usr/lib64/libiscsi.so.0
...

I'd rename _that_ library to be libiscsi-initiator-utils.so, to
reflect the name of the package in question, since it - again -
_appears_ to be package-specific.


Thanks,
