Right, because bootstrap only checks the additional rocks required to bootstrap the project... install-time checking is performed by luarocks, and runtime checking by std.string.require_version.  Unfortunately, the latter two don't give such overtly long diagnostics.

stdlib-37 was announced (twice!) on luarocks-develpers and lua-l, awaiting upload to the luarocks repo by Hisham.  In the mean time, it's available in the usual place:

   http://raw.github.com/rrthomas/lua-stdlib/release/stdlib-37-1.rockspec

OK, I've installed that.

By the way, now that a) there are quite a few programs using stdlib (at least of ours!) and you've started making definite backwards-incompatible changes, might it be time to adopt semantic versioning? Even if (so far) we can't actually use it.

 

As to building zile from your github repo; I did ./bootstrap && ./configure, and then:

Why is it trying to load modules from my installed zile???

Having uninstalled the zile rock (and updated all my code to use optparse and stdlib 37), I can now reproduce your nasty errors.
