What is the test that it's failing? That's a big hint right there.

Also, you can do something like
Code:
strings devbinary > strings.dev
strings buildbinary > strings.build
diff -u strings.dev strings.build

Another thing, your system can prelink binaries, which results in a change to the binary itself, so if the md5sum of the binary on both boxes is different, it might only be because of the prelinker. See man prelink.

Lastly you might want to try:
Code:
rpm -qa --qf "%{NAME}-%{VERSION}" | sort > rpmlist.hostname

on both hosts and then diff the results.

XDIFF_STRING_RABDIFF(3) 						 1						   XDIFF_STRING_RABDIFF(3)

xdiff_string_rabdiff - Make binary diff of two strings using the Rabin's polynomial fingerprinting algorithm

SYNOPSIS

       string xdiff_string_bdiff (string  $old_data, string  $new_data)

DESCRIPTION

	Makes  a  binary  diff	of two strings and returns the result. The difference between this function and xdiff_string_bdiff(3) is different
       algorithm used which should result in faster execution and smaller diff produced. This function works  with  both  text	and  binary  data.
       Resulting patch can be later applied using xdiff_string_bpatch(3)/xdiff_file_bpatch(3).

	For more details about differences between algorithm used please check libxdiff website.

PARAMETERS

	      o $old_data
		- First string with binary data. It acts as "old" data.

	      o $new_data
		- Second string with binary data. It acts as "new" data.

RETURN VALUES

	Returns string with binary diff containing differences between "old" and "new" data or FALSE if an internal error occurred.

SEE ALSO

       xdiff_string_bpatch(3).
