title: Warning in system("sh ./configure.win") : 'sh' not found
body: <p>I am trying to install the package "RODBC" on my laptop.
  However, I get the following error when trying to install the package.<a href="https://i.stack.imgur.com/j47yv.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/j47yv.jpg" alt="enter image description here"></a></p>
  
  <p>I have googled around a bit, but couldnt find anything particularly helpful for my case.</p>
  
  <p>The only thing I could find was that currently the package is only applicable for R-versions greater than 4.0. However, I also installed this package a few weeks ago on another laptop (with a version lower than 4.0), and I did manage to install the package on that laptop. </p>
  
  <p>Any help would be appreciated :) </p>
