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 libarpack.so -> libarpack.so.9
-rwxr-xr-x 1 rt users 350904 Nov 16 23:46 libarpack.so.0.9.2
lrwxrwxrwx 1 rt users     18 Nov 16 23:46 libarpack.so.9 -> libarpack.so.0.9.2
rt [ ~ ]# 


rt [ ~ ]# ls -l  /usr/local/algebra/lib/libumfpack*
lrwxrwxrwx 1 root root     15 Nov 17 12:49 usr/local/algebra/lib/libumfpack.so 
-> libumfpack.so.5
lrwxrwxrwx 1 root root     19 Nov 17 12:49 
usr/local/algebra/lib/libumfpack.so.5 -> libumfpack.so.5.2.0
-rwxr-xr-x 1 root root 708862 Nov 17 12:44 
usr/local/algebra/lib/libumfpack.so.5.2.0
rt [ ~ ]# 
rt [ ~ ]# ls -l  /usr/local/algebra/static_lib/libumfpack*
-rw-r--r-- 1 root root 1328178 Nov 17 12:45 
usr/local/algebra/static_lib/libumfpack.a
rt [ ~ ]# 
--------------------------

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

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


-------------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 
appreciasted.
