ExitFailure 9 al intentar instalar ghc-mod utilizando Cabal (1)

Cuando trato de instalarlo con cabal, me sale

No estoy muy seguro de a dónde ir desde aquí. ¿Cómo puedo saber más sobre por qué falló?

edición: estoy usando GHC versión 7.4.1 y Cabal versión 1.14.0

Correr Cabal en modo detallado no parece dar ninguna pista excepto:

... World file is already up to date. cabal: Error: some packages failed to install: ghc-mod-1.11.1 depends on haskell-src-exts-1.13.5 which failed to install. haskell-src-exts-1.13.5 failed during the building phase.

Resultó ser un problema de falta de memoria, como Hammar sospechaba. Pude instalarlo (aunque fue muy lento) al agregar un archivo de intercambio de 1GB al sistema:

dd if=/dev/zero of=/swapfile bs=1M count=1024 mkswap /swapfile swapon /swapfile

Aparentemente las instancias de EC2 vienen sin swap por defecto.
