Crystal installation using Linuxbrew is not working

I submitted a patch to the homebrew formula:

github.com/Homebrew/homebrew-core

crystal: Set `CRYSTAL_CONFIG_LIBRARY_RPATH`

Homebrew:master ← straight-shoota:patch-3

Programs build with a crystal compiler from homebrew fail to execute because som…e libraries can't be located: ```console $ docker run --rm homebrew/ubuntu22.04 # brew install crystal # crystal run 'puts %(hello world)' /home/linuxbrew/.cache/crystal/crystal-run-eval.tmp: error while loading shared libraries: libgc.so.1: cannot open shared object file: No such file or directory ``` Note this affects the program runtime, not the compiler itself. Binaries need to know where to find their binaries. The linker is told to look in homebrew's lib path via `CONFIG_LIBRARY_PATH`. But at runtime the loader doesn't have this information. It can be baked into the binary via `CONFIG_LIBRARY_RPATH`. Issue report: https://forum.crystal-lang.org/t/crystal-installation-using-linuxbrew-is-not-working/6559
