I fear there may be something more seriously wrong. I have installed DrRacket 5.1.3 on a PPC Mac running Leopard (which I can't appropriate full-time), and it seems to work fine there too.
I have installed DrRacket 5.1.3 on my little-used (because I find it annoying) Windows laptop, and "Add Teachpack" is one of the available options on the Language menu. It appears to work fine. On my machine (PB G4, Tiger), I moved Rackets from Applications to Trash, and re-extracted the zip file into Applications. Same result as before: the Language menu does *not* include a pane for "Add Teachpack." Based on comparing md5's, the zip file I installed from both times on my Tiger machine was identical to the zip file I downloaded fresh from the Racket site. The Teachpacks themselves are not missing, I can load them into the definitions window from the collects/teachpack/htdp/ directory, with mostly acceptable results: as long as I include subsequent definitions within the "module" function of that teachpack, things appear to work, though I'd be less than surprised if something failed later on. Does anyone out there know firsthand if DrRacket 5.1.3 works in general, teachpacks and all, on MacOSX Tiger PPC? That is, whether what I'm seeing indicates a general failure on Tiger (PPC) or just a failure on *some instances* of Tiger, including mine? And yeah, I know, the war's over, Intel won, and here I am wandering the jungle, with my Tiger. And I'm covered in monkeys. -jmc On Thu, Sep 1, 2011 at 3:42 PM, Robby Findler <ro...@eecs.northwestern.edu> wrote: > The menu item, however, should be available in all languages. > > Are you sure you're using a recent version of DrRacket?
