It seems that DB_File checks the running version of libdb against what
was compiled against.

This check is exact:

    if (Major != DB_VERSION_MAJOR || Minor != DB_VERSION_MINOR
                || Patch != DB_VERSION_PATCH)
        croak("\nDB_File needs compatible versions...");

To make the behaviour match libdb4.3.shlibs I could probably change the
last test to "Patch >= DB_VERSION_PATCH".

Two questions for the libdb4.3 maintainers:

  * Is the ABI stable b/w patch revisions?
  * Why does libdb4.3 4.2.29-1 have 4.2.28-1 in the shlibs file?
