What a nice error message ! (this wil be improved soon ;) ).

This error happens because ldd encountered an unexpected line.
In that case, we should figure out if this line is the sign of a problem or
not:
  - if this is not a problem, we should ignore it when parsing ldd output
(modification to be done in checkpkg code),
  - if this is a problem:
         - either we let the error be raised so that the maintainer is
warned that something is wrong,
        - or better we store the information in the checkpkg database and
add a real check about this issue.

Well I am not sure it is fine.
It usually means that, to be run, your binary requires a system with
hardware capability AMD_3DNOW.
See: http://docs.oracle.com/cd/E19082-01/819-0690/chapter2-20/index.html

I am not sure we want that for our binaries. Are there still a lot of
computers without this capability ?

But maybe this is just an optional feature, I have to check exactly how it
works.
Are you able to run the resulting binary on a system without AMD_3DNOW
capabilites ?

Do I have a direct access to the location where you built it so I can skip
the building step ?
