Xerces is not required in order to run GNU Radio binaries. I'm not sure about 
the exact purpose of xcerses in connection with GNU Radio - documentation?.
It is not missed here.

When upgrading a system this way, one has to ensure that all files of the old 
packages are getting uninstalled and all dependencies are updated as well. 
Mixing old and new binaries and libraries can cause havoc to the system.

Using a good packaging system. that keeps track of package dependencies is the 
only safe way of upgrading packages.
