Compilation failed with error: `use of unstable library feature 'int_log'`

Hi, I am attempting to make a Docker image for GGCAT, and I get this result when building:

#0 91.42    Compiling instrumenter v0.1.1 (/software/ggcat/libs-crates/instrumenter-rs)

Any ideas what's going on? This image is built on top of the official Ubuntu 22.04 image with minimal other additions to the environment.

Thanks

Just kidding, I fixed it by installing rustup
