Seems I had  some fortitious beginners luck  and half a day descended as 
manner from heaven   as it   just   'compiled' with the libumfpack and 
libcholmod  et al  prepared as described previously.  

The other half   is unmade.   It will not compile with arpack that has been 
compiled and linked with lapack-3.2.2 and atlas3.9.32.  I tried both and libarpack.a. The  config.log  entries  respectively are:-

--for 'undefined rererence to 'etime_'.
--for libarpack.a:- (arscmd.f   in function 'asrscmd_'  
arscmd.f :(text+0xe) undefined reference to 'etime_'

suggestion for my other good half a day will be gratefully received
