After a lot of to-ing and fro-ing I think I have found a resolution.  AND it 
does net seem to be related to  having shared libraries.  

In a nutshell, Scilab-5.2.2  seems to require the now ageing components of  
SuiteSparse-3.4.0 and I was using the new{er/est} components.  (The latter for 
example  has  UMFPACK-5.5..0 with at  least one  source file umf_cholmod.c (or 
some such) not in the UMFPACK  in the  ageing  SuiteSparse-3.4.0.). 

This is the narrative:-

-- I compiled both shared libraries and static libraries of the new components 
and   the scilab-5.2.2  configure script failed  complaining it cound not find 
umfpack.h

--I    set CPPFLAGS to point to the OLD (i.e. as in SuiteSparse-3.4.0) 
umfpach.h  with NEW  (i.e. from UMFPACK-5.5.0)  libumfpack..a and   the 
configure script generated Makefiles and a successful scilab-5.2.2 build 
resulted

--I rebuilt SuitSparse-3.4.0     with both sharedlibs and static libs  AND  
the Scilab-5.2.2 configure script failed with shared libs but  the build 
succeed with static libs.

perhaps you shoud update  scilab  upstream so that  the newer components of 
SuiteSparse  can be used.
