Build failures on MacOS 10.14.4

[typeless]

Is that because I cannot declare pkg ... in a file along with main?

The code:

use std
use testr

pkg dfspath =
        type dfspath = struct
                source  : int
                marked  : std.bitset#
                adj     : int[:][:]
                graph   : int[:][:]
        ;;

        const mkdfspath : (g : int[:][:], s : int -> dfspath)
        const dfspathfree : (dp : dfspath -> void)
;;

const mkdfspath = {g, s
        var dp

        dp.source = s
        dp.marked = std.mkbs()
        dp.adj = std.slzalloc(g.len)
        dp.graph = g
        -> dp
}

const dfspathfree = {dp
        std.slfree(dp.adj)
        std.bsfree(dp.marked)
}
const main = {
        testr.run([
                [.name = "mytest", .fn = test1]
        ][:])
}

const test1 = {ctx
        const s1 = [
                .[0] = [1, 2][:],
                .[1] = [2, 0][:],
                .[2] = [0, 1][:],
        ][:]


        std.put("Hello World\n")
        testr.ok(ctx)
}

This will not happen if I follow the idiomatic way to write tests as the std libs do.
A better error message by the compiler would be helpful.

This issue no longer exists.
