Compilation error

[achirkin]

Hi tolysz! Many thanks for such an initiative!
I followed your suggestion to use your source to have GHCJS aligned with stack:
resolver: lts-5.1
compiler: ghcjs-0.2.0.9005001_ghc-7.10.3
compiler-check: match-exact
setup-info:
ghcjs:
source:
ghcjs-0.2.0.9005001_ghc-7.10.3:
url: "https://tolysz.org/ghcjs/lts-5.1-9005001.tar.gz"

However, I got a following error:

Cabal-1.22.7.0: copy/register
Progress: 40/56

     Logs have been written to: /home/achirkin/.stack/programs/x86_64-linux/ghcjs-0.2.0.9005001_ghc=7.10.3/src/.stack-work/logs/cpphs-1.19.3.log

Here are the logs:

Configuring cpphs-1.19.3...
Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.

    old-locale-1.0.0.7-8d155d9be6e318869cf152bd0c621225 is shadowed by package old-locale-1.0.0.7-0db938eb141b01f4936a21aef6b843bf
    (use -v for more information)

So looks like the problem is that package old-locale gets compiled twice;
even though it is the same version, random ids differ and cause an error.
Where should I look into to try to resolve this issue?

I test it my code works by using:
https://github.com/tolysz/video/blob/ghcjs/client/build2.sh
within client folder
With an updated stack.yaml from that folder
