Description
In #72 I had a problem getting dotnet to work after installing dotnet-install.sh because dependencies were missing. After discussion the decision was to stop attempting to check for dependencies and instead include a URL in the console output.
Unfortunately, even I myself 1 year on hit this again and did not notice the URL. Here's the output

I didn't read this -- am I typical? Eg., I don't read all the output from "apt-get".
Then got stuck puzzling out why dotnet didn't work, because in my mind, the script is "make_dotnet_work_anywhere.sh"

The fix for this was apk add libstdc++ and apk add libgcc. Of course there are several other dependencies, listed at the URL above.
@ericstj's suggestion is to somehow maintain a list of dependencies where the install script can read them from. @leecow I wonder whether that would make sense. It's a super unfriendly experience for someone wanting to get started.
