I found it best to install the current version (2014.2.0.0) of Haskell
Platform first.  Then, when I tried to install Agda, it aborted with a
complaint about the version of cpphs, so I had to do

cabal install 'cpphs < 1.19'

After that,

cabal install

in the Agda source directory worked as expected.  (Alex in HP is at
version 3.1.3, which is acceptable to Agda.cabal.)

Cheers,
Raghu.
