xfce 4.10 upgrade error

["G"]

Hi

I am trying to upgrade to xfce 4.10. I am using fedora 16 64 bit. I am
trying this upgrade using yum by copying the repo file from Kevin's repo. I
get couple of errors while upgrading. Please find attached the file which
contains the error.

Any help on this is greatly appreciated.

Thanks,
Cheers,
