Gzip error when trying to install from source with OTP version

[jswny]

I can install Elixir from source like so with no issue: asdf install elixir ref:v1.8.1. However, when I try to install it from source with a specific OTP version, I get an error:

$asdf install elixir ref:v1.8.1-otp-21

I already have OTP 21 installed via ASDF, so maybe I am misunderstanding compiling Elixir with the right OTP version and I don't need to specify that when compiling from source since it will use the OTP version I have installed but I am not sure about that. I assume I would have to specify the OTP version in the install command since it can download a file with the Elixir source for that specific OTP version.

Please correct me if I'm doing something wrong here. Thanks for all of your work on this great plugin!

When you use the ref:<version> syntax the value must be a Git reference in the repository. In this case no such ref exists.

We should improve error logging here and print a readable message when the reference is not found.
