  Everything is fine until I compare the md5sums of

At that point, even if we know that they did not change, the sums are
different. The rpm's were
built using the same library file that was built with the ver. 000. The
library files were only
Included in with the rpm and not a newly rebuilt file. Note that the
library file is not only
Different form ver 1 and 2 but also from the original.

Question:
1. What is causing the rpm to change from the original to each version?

Sometimes developers or the build process puts time and date or version
specific info into a file.  For example, if you build the same rpm twice
in a row, the rpm itself will be different on each run, because the
"build date" info will be different.

2. How could we compare the library files from each rpm to determine if
they changed since
   the md5sums are different?

Well, if the md5sums are different, you've already determined that the files
have changed.
