post installation log file queries relating to previous driver (5328)

[helios]

I just upgraded to the latest 5336 drivers with no problems; graphics work fine. However, upon perusal of the /var/log/nvidia-installer.log file I noticed the following messages:

-> Validating previous installation:
-> The previously installed file '/usr/lib/tls/libGLcore.so.1.0.5328' has a
   different checksum (3880335966) than when it was installed (2303922136). 
   /usr/lib/tls/libGLcore.so.1.0.5328 will not be uninstalled.
-> The previously installed file '/usr/lib/tls/libGL.so.1.0.5328' has a
   different checksum (2612725697) than when it was installed (324366836). 
   /usr/lib/tls/libGL.so.1.0.5328 will not be uninstalled.

   checksum (3128962176) than when it was installed (155884629). 
   /usr/bin/nvidia-installer will not be uninstalled.
-> done.
WARNING: Your driver installation has been altered since it was initially
         installed; this may happen, for example, if you have since installed
         the NVIDIA driver through a mechanism other than the nvidia-installer
         (such as rpm or with the NVIDIA tarballs).  The nvidia-installer will
         attempt to uninstall as best it can.  Please see the file
         '/var/log/nvidia-installer.log' for details.

I also got that WARNING message whilst running the installer, but it didn't prove to cause any problems. And as suggested in the warning, I haven't installer the NVIDIA driver through any other methods. Is it safe to ignore these messages? Or preferably, can I manually delete the files mentioned above (libGLcoreso.1.0.5328, etc.) without any resulting issues?

Thanks in advance.

DIsregard this. I uninstalled the driver, then reinstalled and the warning went away..
