I have tried using `--force` and the flag Guillaume Piolat 
suggested. Unfortunately, both solutions did not solve the 
problem. Johan's suggestion gave some insights:

```
$ file `which dub`
/usr/local/bin/dub: Mach-O 64-bit executable x86_64

$ file /usr/local/homebrew/Cellar/ldc/1.35.0/bin/ldc2
/usr/local/homebrew/Cellar/ldc/1.35.0/bin/ldc2: Mach-O 64-bit 
executable arm64

$ file `which ld`
/usr/bin/ld: Mach-O universal binary with 2 architectures: 
[x86_64:Mach-O 64-bit executable x86_64] [arm64e:Mach-O 64-bit 
executable arm64e]
/usr/bin/ld (for architecture x86_64):	Mach-O 64-bit executable 
x86_64
/usr/bin/ld (for architecture arm64e):	Mach-O 64-bit executable 
arm64e
```

I will try to get a arm64 version of DUB. Once I have done that, 
I will give an update.
