The package setup script has attempted to modify files on your system
that are not within the EasyInstall? build area, and has been aborted.

This package cannot be safely installed by EasyInstall?, and may not
support alternate installation locations even if you run its setup
script by hand. Please inform the package's author and the EasyInstall?
maintainers to find out if a fix or workaround is available.

Please send this kind of request to the mailing list.
It is not clear that this is a software bug, on the contrary, this looks more like a packaging issue with one of the dependencies.
Have you tried disabling SELinux?

SElinux is disabled. But i updated setuptools and it is working now
