Hello, I have had this same problem when I was upgrading Racket from 6.8 to 6.9, and now again when upgrading from 6.9 to 6.10. Basically what happens is that raco downloads and installs all packages as if they were for the previous version of Racket.
I installed Racket as 'brew install minimal-racket' and it installed Racket under `/usr/local/Cellar/minimal-racket/6.10/` as expected. Next, I ran `raco pkg install --auto drracket` and what happened was that raco downloaded the packages for the 6.9 release and installed them under `/usr/local/Cellar/minimal-racket/6.9/`. I checked and that directory indeed did not exist prior to running raco. This messes up things because now Racket and raco get confused. At first everything runs normally, but after running `raco setup` (to update a package I have been developing locally) the symlink to the `raco` binary is gone from `/usr/local/bin`. The binary is still there in the `6.10/bin` directory though. There is probably even more things messed up, but raco was the first one I noticed. I had the same problem when I was upgrading from 6.8 to 6.9 and I don't know what made it go away. Is this a Racket problem or a Homebrew problem? My bet is on Racket since the initial installation seems to be proper, but maybe Homebrew compiled Racket with the wrong options? Any ideas what could be going on here? I know that there is a cask, but I prefer to install software the Unix way. Thanks in advance. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
