Installation failure

The installation command
```
git clone https://github.com/cloudflare/slirpnetstack
cd slirpnetstack && make

```
gives the error:

> package github.com/cloudflare/slirpnetstack
> imports gvisor.dev/gvisor/runsc/specutils
> imports gvisor.dev/gvisor/runsc/config

> make: *** [Makefile:9: bin/slirpnetstack] Error 1

When we try to do `make update-gomod`, we receive the errors:

How can we install it?
The last commit seems to be 3 years ago, with this question I'm also testing whether the project is still maintained? Thank you
