The script looks correct now. Here's the summary of what changed and why:
scripts/install_nim.sh — two changes:
Moved NIM_DEST definition to the top (line 20), before the early-exit check that references it.
Replaced the early-exit condition. The old logic checked nim --version in PATH and exited if it matched — including a silent exit for "newer version already installed". The problem: on the Linux machine, nim 2.2.4 was installed by the system package manager at a non-standard path (e.g. /usr/bin/nim or /nix/store/…). The script saw the right version and exited early, but ~/.nim/nim-2.2.4/ was never created. Later, when nimble fell back to downloading nimble 0.22.3 source and compiling it, nim looked for its stdlib at ~/.nim/nim-2.2.4/lib/system.nim — which didn't exist.
The new logic: only skip if ${NIM_DEST}/lib/system.nim actually exists (i.e. we installed it there). If it does, re-create the ~/.nimble/bin/ symlinks just in case they're stale, then exit. Otherwise, always download and install to ~/.nim/nim-2.2.4/, creating a self-contained installation the rest of the build can rely on.
