ruby gem ffi dependency has no prebuilt binary and compiles at installation time

[korniltsev]

which can fail if there are not compiler or ruby headers

steps to reproduce:

1. get a fresh ubuntu 22.04
2. install ruby
3. gem install pyroscope --verbose

For this kind of issue, you need to say which hardware platform and ruby version you are using.

https://rubygems.org/gems/pyroscope shows gems with precompiled binaries for x86_64-linux and aarch64-linux. Ubuntu 22.04 is glibc-based, IIRC, so if you have one of those hardware platforms then it should work. If it doesn't work, then we need enough information to replicate the issue.

it is x86_64-linux glibc

The issue is not with the pyroscope depdendency - this one is pulled as a correct arch specific binary.
The issue is with the ffi dependency of pyroscope which is not downloaded as a binary
