use -X

-X uses stat and that takes quite a long time, especially on Win32. It leaves the possibility that between your failed attempt and the return of the test, another program (or another copy of this program), will get in and create the directory.

But as javafan pointed out, that isn't necessary. $! tells me the reason for failure. See Re^4: Generate a unique ID.

[stevieb]: I've finally added the ability for berrybrew to fetch the list of perls available directly from Strawberry's releases.json file. Instead of pulling from there on every single call, I've added a berrybrew fetch, so it's only updated..
[stevieb]: ...on request. There's some supporting work I need to do, as well as update the docs, but it's in the v1.12 branch if anyone wants to play with it...
[stevieb]: ...issue 62 will track what else needs to be done.
