I am using cblfs compiled from sources  and 64-bit non multilib.  Here is an 
update  I had prepared to post   to the maintner list I hoped to join:-

I am compiling   on a machine with the following:-
----cpu  amd64 2cores
----o/s cblfs linux 64-bit  non-multilib kernel-2.6.32, gcc-4.4.2
----BLAS: atlas3.9.32  SuiteSparse-3.4.0 lapack-3.2.2 arpac-0.92 (autoconf'ed)

AND this is what happens:-
Both SuiteSparse and arpac are  compiled to give  shared and statc libs and 
linked to  atlas and lapack libraries.  They are available at the locations 
shown below:-

---------------- arpack and umfpack locations:-
rt [ ~ ]# ls -l /home/rt/ArpackTEST3/lib
total 1000
-rw-r--r-- 1 rt users 662720 Nov 16 23:46 libarpack.a
lrwxrwxrwx 1 rt users     14 Nov 16 23:46 ->
-rwxr-xr-x 1 rt users 350904 Nov 16 23:46
lrwxrwxrwx 1 rt users     18 Nov 16 23:46 ->
rt [ ~ ]# 

rt [ ~ ]# ls -l  /usr/local/algebra/lib/libumfpack*
lrwxrwxrwx 1 root root     15 Nov 17 12:49 usr/local/algebra/lib/ 
lrwxrwxrwx 1 root root     19 Nov 17 12:49 
usr/local/algebra/lib/ ->
-rwxr-xr-x 1 root root 708862 Nov 17 12:44 
rt [ ~ ]# 
rt [ ~ ]# ls -l  /usr/local/algebra/static_lib/libumfpack*
-rw-r--r-- 1 root root 1328178 Nov 17 12:45 
rt [ ~ ]# 

I  then   ran the configure script  for octave-3.3.53 with the folowing 

--with-umfpack-includedir=/usr/local/algebra/include \
--with-umfpack-libdir=/usr/local/algebra/static_lib \
--with-arpack-libdir=/home/rt/ArpackTEST3/lib \

-------------it responds as shown below:-
configure: WARNING: UMFPACK not found.  This will result in some lack of 
functionality for sparse matrices.
configure: WARNING: ARPACK not found.  The eigs function will be disabled.

The rest of the SparseSuite components including libcholmod are found  but not 
umfpack.  Also if arpac is compiled and not linked to atlas   it is  'found'.
  I am wondering if there is a problem  octave-3.3.53 has with libraries 
already linked to atlas and lapack (compiled with gfortan) and if there is 
whether a fix upstream exists or otherwise.

I very much want to have  octave   compiled with umfpack and arpack 
functionality  and linked to BLAS and LAPACK libraries so advice would be
