How to verify a detached signature in an embedded device

Hello,

I built the binary elfsigchk and made a test with 
bin2array as a elf executable:

// First, I create the detached signature bin2array.sig
$ gpg -sb bin2array

// The I want to verify it with elfsigchk
$ ./elfsigchk bin2array bin2array.sig
signature is NOT valid: no signature found

It always returns: no signature found. Why???
Is there a version problem (I use 1.0.4)? 

Thanks, 
Peter
