Thanks! No problem. I gave a try to your suggestion. It doesn't look I'll get yesod installed without "paying"
a bigger price than just "downgrading". :-/
Yesod 1.4.0 warns that forcing installing it will likely break pandoc, among other things.
I can give it a try though, but I really use pandoc regularly. Plus, it's still not clear that the building process
will not fail. And installing pandoc took me surprisingly a lot of time last time.
Forcing Yesod-1.2.6.1 won't allow cabal to satisfy the dependencies.
I guess I could keep trying other versions and see. But I think I'll try the 1.4.0 first. Will post here
the results so that at least others may hopefully benefit from this.
