@chetmurthy any chance you'd know why pa_ppx.0.03 is failing here?

Oops, sorry, just woke up. This is almost certainly b/c pa_ppx has to have copies of ocaml and camlp5 AST types: there's a mechanism for [at development time] generating them, storing in numbered directories, and then [at install time] fetching the correct version. I'm guessing something broke. Since your dep change fixed the problem, and 0.03 is a pre-release anyway, I'll leave things be.

[chetmurthy]

Now that I'm fully-caffeinated, I'll take a look and just make sure that there wasn't anything else wrong, and that whatever-it-is, it's resolved with the latest pa_ppx release.

[chetmurthy]

OK, that's definitely a bug in the method by which I determine which generated-source to pull during the install process. Thanks for pointing me at this! I'll fix this in the latest version of pa_ppx. Ugh.

Found and fixed in pa_ppx.
