ruby and kdebingings-4.4.5

[lI]

Greetings  

I am trying top compile kdebindings-4.4.5. on a pure 64bit clfs linux machine.  
The compilation  progresses to ~73 prcent  then fails :-

[ 73%] Building CXX object

I have ruby-1.9.1-p376 installed in /usr  and   the said installation does  
not  appear to have 
--env.h, 
--mode.h ,
--version.h 

headers  files.  The header files I have are shown below:-
