example failed to run on zig 0.11.0-dev.1384+fe6dcdba1

After fixing all FileSource from .path to .source, I still can't compile this package.
I keep having this error:

examples/text_extents.zig:34:29: error: root struct of file 'cairo' has no member named 'Surface'
    var surface = try cairo.Surface.image(width, height);

I got all tests passed on zig version 0.11.0-dev.939+5bde627f9 after i changed:

usingnamespace @import("surfaces/surface.zig");

to

pub usingnamespace @import("surfaces/surface.zig");

edit: seems like all usingnamespace exports in cairo.zig could use the pub keyword.
I don't know if pango was left out intentionally but i've also appended:

pub const Pango = struct {
    pub usingnamespace @import("pangocairo.zig");
};

to the same file.

I'm a zig-newb, very dislike LSP, but it's a tiny bit nice when new/typed-language.

I've noticed that zls shows no suggestions when:

pub usingnamespace @import("surfaces/surface.zig");

versus

pub const Surface =  @import("surfaces/surface.zig").Surface;

Can somebody explain to me what's going on here?
I see both patterns in zig std; what's the best approach for a zig-library?

Edit: NVM, i accidentally jumped to conclusions. both patterns same result. no err.
