Description Tim McConnell 2006-12-18 14:10:27 EST
Description of problem:
SELinux denied access requested by /usr/sbin/prelink. It is not expected
    that this access is required by /usr/sbin/prelink and this access may signal
    an intrusion attempt. It is also possible that the specific version or
    configuration of the application is causing it to require additional access.

Allowing Access
    Sometimes labeling problems can cause SELinux denials.  You could try to
    restore the default system file context for powermanga, restorecon -v
    powermanga If this does not work, there is currently no automatic way to
    allow this access. Instead,  you can generate a local policy module to allow
    this access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385
    Or you can disable SELinux protection altogether. Disabling SELinux
    protection is not recommended. Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

What is the path to powermanga?  If you chcon -t bin_t powermanga this problem
will go away.
