Steps to reproduce

Example from the Modular website: Modules and Packages

__init__.mojo

from .mymodule import MyPair

mymodule.mojo

struct MyPair:
    var first: Int
    var second: Int

    fn __init__(inout self, first: Int, second: Int):
        self.first = first
        self.second = second

    fn dump(self):
        print(self.first, self.second)

main.mojo

from mypack import MyPair

fn main():
    let mine = MyPair(2, 4)
    mine.dump()

This example also includes a .mojopkg as well

System information

- What OS did you do install Mojo on ?
    Archcraft x86_64: 6.7.8-arch1-1
- Provide version information for Mojo by pasting the output of `mojo -v`
    mojo 24.1.0 (c176f84d)
- Provide Modular CLI version by pasting the output of `modular -v`
    modular 0.5.1 (1b608e3d)

[sneekyfoxx]

The mypack.mojopkg was built with an older version of mojo and the let keyword should have been var instead. Everything works fine so I'm closing the issue. Sorry for the inconvenience.
