I had no such error, applying the 
realtime-preempt-2.6.12-rc5-V0.7.47-15 patch to rc5-git5 (other than 
the Makefile, easily fixed, and lib/Kconfig.debug, as git5 had 
already played with the location of the frame pointers option.  I 
left it at the git5 level, seemed to work.  Its built, but not 
rebooted to, working on wedding photo's for the neighbors ATM.

I used the "linux-2.6.12-rc5-git5-RT-V0.7.47-15" throughout _my_ 
scripts and the Makefile as the version number.  I note your error 
messages seem to indicate a miss-match there.

So many thanks to the original poster, whose message prompted me to 
take another swing at it.
