rise-vpn fail to compile

On a gentoo system with go1.11.4, and I get some hard time to compile riseup-vpn_package. It seam to be related to errors in the README.md file.

1. git clone 0xacab.org/leap/bitmask-vpn fail because the url doesn't exist. I used git clone https://0xacab.org/leap/riseup-vpn_package.git instead.

2. cd bitmask-systray Same thing, it was cd riseup-vpn_package

3. go get . work, nice!

4. go build fail to find 2goarray

5. go get -u golang.org/x/text/cmd/gotext github.com/cratonica/2goarray work fine

6. go buld doesn't find 2goarray again. I am a go newbie and had to figure out than 3 more commands was needed before 3.:

export GOPATH=${HOME}/softs/go
mkdir $GOPATH
PATH="$PATH:$GOPATH/bin"

but now go build fail with:

go build
can't load package: package 0xacab.org/leap/bitmask-vpn: unknown import path "0xacab.org/leap/bitmask-vpn": cannot find module providing package 0xacab.org/leap/bitmask-vpn
