Sorry about that breakage. (Details in rest of paragraph) The old stack ide targets command prints error messages along with 'real' output to stderr, making it hacky to get the output, so when I learned that it was possible to have it switch to stdout, I just used it. Apparently I didn't consider that it broke pre-2.1.1 users. This is a oversight on my part.

I'll probably put the original behavior back since it does work, and also probably document version requirements and put in checks after I do determine the actual needed versions.

But meanwhile if your setup is compatible (it's private, but I don't see why it wouldn't be), just upgrade to the latest version of stack. Yours is nearly a year old now (assuming you meant 1.9.3).
