</div>If you don't want to use it, then it's safe to hide it:<br>
<br>
ghc-pkg hide unix-2.3.0.0<br>
<br>
You can always unhide it later.<br>
<br>
You can also tell ghc to use a specific version of a package:<br>
<br>
ghc -package unix-2.2.0.0<br>
<br>
Of course, you'll need to make sure unix-2.2.0.0 is registered with ghc-pkg.<br>
