texmath-0.8.3 fails to install via cabal

I haven't seen this before, but it seems others have
encountered a similar problem with other packages:

ekmett/lens#407

Here they suggest ensuring that you haven't installed a new
version of template haskell on top of the one that goes with
your version of the compiler. Can you confirm that?

ghc-pkg list template-haskell

Hi, I'm trying to install pandoc via cabal and the installation fails
when trying to install texmath. Some possibly relevant version numbers:

$ cabal --version
cabal-install version 1.16.0.2
using version 1.16.0 of the Cabal library
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.6.3

I'm working on Ubuntu 14.04.

Here's what I get:

$ cabal install pandoc

pandoc-1.15.0.6 depends on texmath-0.8.3 which failed to install.

Does anyone have some advice? Thanks for any light you can shed on this
problem.

best,

Thanks for the pointers. They suggest at one point that the problem might be a version mismatch between Template Haskell and GHC -- versions are correctly matched on my system. At another point it's suggested to install from a Git repo, so I tried cloning texmath and then cabal install from there. That worked, which is a little surprising since the Git version is apparently 0.8.3 which is the same as what cabal install texmath was trying to install. Anyway I guess the problem is resolved so I'll close this issue.
