Totally, upgrading your frameworks should not need you to recompile or upgrade 
unrelated nor related stuff.

Note that in this case (kglobalaccel) you don't need to do nothing, it just 
overwrites whatever was there on plasma, so it is more a packaging issue 
(packaging doesn't like two packages to write the same file to the same place 
even if it's the same file) than a recompiling/upgrading thing.
