version mismatch message about b2

[grafikrobot]

If you install b2 it can be easily cached without version mismatches. So not sure what you are asking for. Also, the bump_version.py script is obsolete and not used any longer.

There was a recent report of the mismatch error: boostorg/url Issue 760

You are suggesting to install b2. Not sure if that's different from building b2, which is what occurs during CI testing.

After building, b2 resides in the boost folder. Installation to /bin/ or /usr/local/bin would not get cached.

I think I have already fixed this by adding new logic in boost-ci. It just seemed that perhaps the comparison check should live in the bfgroup/b2 repository instead of boostorg/boost-ci . Otherwise, it's ok to close the issue.
