When trying to install development tools I get the following error.
> The following packages could not be found on your system. Installation
cannot continue until they are installed.
> libselinux ('system-config-securitylevel', '1.4.18','2')
> libxml2 ('libxml2-python','2.6.16','3')

When I do a locate :

]$ locate libselinux
/lib/libselinux.so.1

]$ locate libxml2
/usr/lib/libxml2.so.2

What happens when you do this:

Do you get a package name back? What about the second file?
If not, they are not installed.

It looks like these files are installes

~]$ rpm -q /lib/libselinux.so.1 --whatprovides
libselinux-1.19.1-8
~]$ rpm -q /usr/lib/libxml2.so.2 --whatprovides
libxml2-2.6.16-3

Your SELinux may be downlevel. You should try to upgrade it.
If I'm reading the versioning right, but I could be wrong. That may be one nine, it may be nineteen. Try to upgrade it, and it will tell you. http://freshrpms.net/
