This is because hSimpleDB doesn't specify version ranges on its
dependencies, when it should. Since hxt changed its module structure
going from 9.0 to 9.1, hSimpleDB doesn't build against 9.0.

You can try to build it by adding '--constraint=hxt==9.0.\*' after
your cabal-install command. You can also ask the author to add version
ranges to the package.
     

Is the escape needed if you're using single quotes?
   

I don't know. I always escape *s in shell commands to be sure the
shell doesn't expand them, but in most of the cases, it probably works
without them. It will likely even work without quotes and without the
escape, unless you have files matching the pattern.
 

The single quote doesn't expand anything, so you don't need to escape the *. Actually, this will result in the backslash also being passed to cabal, so I would be surprised if your command works at all.
