I have managed now to install this on a machine with  ghc-7.10.2.

I use  Development Standard library of  December 18, 2015.

Then, applying 

      agda $agdaLibOpt +RTS -M... -RTS  List/Sorting.agda

to my program, I observe that Agda first type-checks Standard library.
At this stage it reports

-----------------------------------------------
  Checking Data.Bin
(/home/mechvel/agda/stLib/dec18-2015/src/Data/Bin.agda).
  Finished Data.Bin.
  Checking Data.List.All.Properties
(/home/mechvel/agda/stLib/dec18-2015/src/Data/List/All/Properties.agda).
/home/mechvel/agda/stLib/dec18-2015/src/Data/List/All/Properties.agda:140,8-14
Failed to solve the following constraints:
  [1147] (x₁ ∷ xs₂) = (_740 ext x xs ¬p) : (List (_738 ext x xs ¬p))
when checking that the pattern (here p) has type
(Any (_739 ext x xs ¬p) (_740 ext x xs ¬p))
------------------------------------------------

So,  agda-unification  is not compatible  with 
Development Standard library of  December 18, 2015
(?)
