Both are 2.6.11.7 (the .config file is identical in both)

No. I just installed and tried this program.

When I do 'prelink -v a.out' I get on one machine:

prelink: a.out: Could not find one of the dependencies
Assigned virtual address space slots for libraries:
/lib/ld-2.3.3.so                                             4f828000-4f83e4f4

...

While on the other I get:

Does that mean the address to which a dynamic library should be loaded is
written in the *.so file? I thought it is determined on runtime when the
program is ran.

How can I change it?
