Update: Taking a look at library/rubinius/configuration.rb it seems that the codedb file may not in fact represent a compressed tape archive. Having noticed that the codelib and stdlib files may represent compressed tape archives, I suppose I'd assumed that this third file for the build would be of a similar format. Assuming it's not a corrupted tape archive - if it's not a compressed tape archive, at all - will return to the porting work, shortly.

2. **What behavior did you expect?**
> The Bzip2-compressed ~tape~ archive file should be readable
3. **What behavior did you get instead?**
> The Bzip2-compressed ~tape~ archive file was not ~completely readable;~ tar ~did not extract any files~
4. **What version of Rubinius?**
> This is in trying to develop a patch for updating the former FreeBSD lang/rubinius port, working with distsrc for Rubinius v5.0
5. **What version of operating system?**
> `FreeBSD riparian.cloud.thinkum.space 12.1-RELEASE-p1 FreeBSD 12.1-RELEASE-p1 #0 8d3f226f4(ci/releng/12.1/patch-with-makefile-hacks: Sat Mar 7 12:38:21 PST 2020 me@riparian.cloud.thinkum.space:/usr/obj/riparian_amd64/usr/src/amd64.amd64/sys/RIPARIAN amd64`
6. **What is your operating system distribution, if your operating system has more than one?**
> FreeBSD 12.1 (local build)
7. **How did you build your version of Rubinius?**
> n/a (working on it, with FreeBSD ports)
8. **Does this issue involve proprietary code?**
> I don't believe it does, though I'm unable to see what's bundled in that specific cache distfile
9. **Are you able to help us debug the issue?**
> Absolutely. ~However, I'm afraid there may not be much I can do for this specific part of bootstrapping the build-tools, at this time.~
> The archive would pass an sha512 check, ~but~ it was not readable to FreeBSD tar
