Description
I don't have a reproducer, although I was trying to build cabal-install with GHC 7.4. For some reason `happy` build failed, and I got:
```
cabal: Failed to build cabal-install-1.25.0.0 because it depends on
cabal-install-1.25.0.0 which itself failed to build.
Failed to build happy-1.19.5. The build process terminated with exit code 127
Failed to build pretty-show-1.6.12 because it depends on pretty-show-1.6.12
which itself failed to build.
Failed to build pretty-show-1.6.12 because it depends on pretty-show-1.6.12
which itself failed to build.
```
These messages are obviously nonsense.
