If you are running debian or fedora there are prebuilt packages for 
umfpack 4.4. As for the configure, I believe you should have written 
something like

export 
CXXFLAGS="-I/home/bekkerd/Downloads/octave/UMFPACKv4.4/UMFPACK/Include/"
./configure 
--with-umfpack="/home/bekkerd/Downloads/octave/UMFPACKv4.4/UMFPACK/Lib/libumfpack.a 
/home/bekkerd/Downloads/octave/UMFPACKv4.4/AMD/Lib/libamd.a"

But if you can use teh fedora or debian packages, because they go to the 
trouble of building shared libraries..

Cheers
David
