Version number issue with snapshot 7.5.0.6

[David Storrs]

read-compiled-linklet: version mismatch expected: "7.5.0.5" found:
"7.5.0.6" in: /Applications/snapshot_Racket_v7.5.0.6/collects/racket/compiled/main_rkt.zo

I'm on OSX 10.11.6 if that matters.

Forgive me if I’m missing something important, but I see messages like this all the time when I’m using two installations of racket simultaneously on one machine. It suggests to me that you need to recompile using a raco make, or just delete the compiled files. Again, apologies if I’m misunderstanding your issue!

I'm not yet able to replicate this problem. Can you say more about
which installer you downloaded and what command you ran to get that
error?

(I tried the current NWU "Racket plus Tests" snapshot, the current Utah
"Racket" snapshot, and yesterday's Utah "Racket" snapshot, all for
x86_64 Mac OS and running `racket` and `drracket`. Installation was by
dragging the folder to my desktop.)

Based on the path name, that ".zo" file really should be version
"7.5.0.6", so I'm not clear on why the executable expects a different
version.

No, you're exactly right, and I'm in the process of compiling. I was
simply surprised that the shipped version (albeit in a nightly
snapshot) had this issue and wanted to call it out.

Huh, odd.

I downloaded https://www.cs.utah.edu/plt/snapshots/current/installers/racket-7.5.0.6-x86_64-macosx.dmg
and I was running a bunch of local-built networking code. I had to do
some faffing about to get PLTCOLLECTS and such set up properly, so it
may be a purely my-problem problem.

One thing I did find odd:

$ which raco
/Applications/snapshot_Racket_v7.5.0.6/bin/raco

$ raco pkg install handy
/Applications/snapshot_Racket_v7.5.0.6/bin/raco: Unrecognized command: pkg

This is probably a mistake on my end, and it may fix itself once the
recompile finishes (maybe?) but why would the pkg command be missing?
