it tries to produce eigs.oct from the source code which is in the  
package and fails because it does not know where libarpack.a is as  
indicated by the error message:

 so no eigs.oct is created

eigs.oct is not in the package tarball it will be in the package  
installation directory after compilation but you won't get it there
until you manage to build it

Set the environment variable LDFLAGS to point to
LDFLAGS="-Lthe/directory/where/you/installed/libarpack.a"
before running Octave and try again
