As I stated, Nim was not installed via these distros, and was being installed per the process given on Nim's website.
Putting in the suggested PATH did solve the problem though, so thanks. $ export PATH=~/nim-0.17.0/bin:$PATH However, this just highlights the inadequacies of the installation instructions|documentation. Instead of the online instruction just saying **"Configuring the PATH environment variable"** it should explictly provide the correct procedure, as given here, which would have precluded this whole confusion and discussion. It's these type of little things that cause unnecessary frustrations and shy people away from using new things. Please think about the things that could potentially go wrong, then create instructions and documentation that will prevent them. Maybe the discussioin on this topic should be put into its own thread so that my original thread topic can remain in focus here.
