haskell IPPrint missing

Hi,

There is a way of coloring ghci input and output, described here. It requires HsColour and IPPrint. The Arch package haskell-hscolour is present, ipprint I cannot find. I tried cabal, but something was wrong. My Haskell is all from reps. How should I be getting IPPrint the right way?

Re: haskell IPPrint missing

I tried stack:

$ sudo stack install ipprint
Writing implicit global project config file to: /root/.stack/global-project/stack.yaml

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for ipprint-0.6:
    sr-extra must match >=1.46.3.1, but the stack configuration has no specified version (latest matching version is 1.46.3.2)
needed since ipprint is a build target.

Some potential ways to resolve this:

  * Recommended action: try adding the following to your extra-deps in /root/.stack/global-project/stack.yaml:

- sr-extra-1.46.3.2

  * Set 'allow-newer: true' to ignore all version constraints and build anyway.

  * You may also want to try using the 'stack solver' command.

Plan construction failed.
$ 

Besides failing, it installed its own version of GHC.

1. How am I supposed to clean up the mess?

2. Well, how to install IPPrint on top of my from-the-official-reps Haskell?
