I am trying to install the Haskell package cpython on Ubuntu 14.04, and I get this error message:
$ cabal install cpython
Resolving dependencies...
Configuring cpython-3.3.0...
cabal: The pkg-config package 'python-3.3' is required but it could not be
found.
Failed to install cpython-3.3.0
cabal: Error: some packages failed to install:
cpython-3.3.0 failed during the configure step. The exception was:
ExitFailure 1
My hypothesis is that it requires python3.3-dev or something similar to be installed, but python3.3 seems to have been removed from Ubuntu 14.04.
