Running tail -f /var/log/messages
When I execute "k9copy" w/o quotes , I get the log in
/var/log/messages. Same happens when running
as SU or user.
From What I can see , I'm having problems with Selinux. How do I
fix it? Relabel etc etc

If you save the relative entries to a text file somewhere and run
"audit2why <name-of-text-file", it'll give you some suggestions.
Actually that will not tell you much. A much better solution would be
to run setroubleshootd. This would translate that error message to
something like the following:
Summary
SELinux is preventing k9copy from loading libk9copy.so.0.0.0 which
requires
text relocation.
Detailed Description
The k9copy application attempted to load libk9copy.so.0.0.0 which
requires
text relocation. This is a potential security problem. Most
libraries do
not need this permission. Libraries are sometimes coded incorrectly
and
request this permission. The
http://people.redhat.com/drepper/selinux-
mem.html web page explains how to remove this requirement. You can
configure SELinux temporarily to allow libk9copy.so.0.0.0 to use
relocation
as a workaround, until the library is fixed. Please file a
http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this
package.
Allowing Access
If you trust libk9copy.so.0.0.0 to run correctly, you can change
the file
context to textrel_shlib_t. "chcon -t textrel_shlib_t
libk9copy.so.0.0.0"
The following command will allow this access:
chcon -t textrel_shlib_t libk9copy.so.0.0.0

Thank you , the chcon command did the job.
