It seems that the rcc&lrelease location points to the temporary rpmbuild 
location instead of the installation one. That's probably a bug indeed, but 
I think gnuplot can easily deal with it:

I see, so I propose the following patch (3 lines added):

   RCC=`$PKG_CONFIG --variable=rcc_location QtCore`
   if test x"$RCC" = x ; then
     if test x"$QT4LOC" != x ; then
         RCC=$QT4LOC/bin/rcc
     else
         RCC=rcc
     fi
   fi
   if ! test -f $RCC ; then
	RCC=rcc
   fi
