Is this because of psuedo or something else?

Everything else is working, so prelink is what fails for me (at least for a simple minimal) build.

any suggestions on how to try and debug further, who might be more familiar with prelink and what its doing?  When I ran readelf -a on ld-2.13.so after prelink was getting weird results, not sure if thats normal or not.
