consts and enums from Nested modules are not seen on FreeBSD

[bakul]

Describe the bug

When a module is two levels deep, its pub const and pub enum values are not seen when this module is included.

Reproduction Steps

mkdir -p foo/bar
cat > foo/bar/bar.v <<EOF
module bar

pub const xyz = 12
EOF
cat > main.v <<EOF
import foo.bar
fn main() {
  println(bar.xyz)
}
EOF
v run main.v

### Expected Behavior

It should print 12

### Current Behavior

On FreeBSD the compilation fails with

error: undefined ident: foo.bar.xyz

It works fine on Ubuntu

### Possible Solution

_No response_

### Additional Information/Context

_No response_

### V version

V 0.4.2 b3d1b04

### Environment details (OS name and version, etc.)

FreeBSD-14.0-STABLE

[spytheman]

run touch v.mod:

The behavior is consistent with that on Linux:

i.e. if you have v.mod at the top of your project, module lookup works.
If you do not, module lookup fails.

[bakul]

I have a v.mod in the same directory! I removed it and did touch v.mod but no such luck. If it matters, v uses clang.

The problem turned out to be an old v.mod in the parent directory. [Just documenting this in case someone else runs into it]

The root cause is "pesky" module lookup (as per @spytheman!)
