Warning: The install command is a part of the legacy v1 style of cabal usage.
Please switch to using either the new project style and the newinstall
command or the legacy v1install alias as newstyle projects will become the
default in the next version of cabalinstall. Please file a bug if you cannot
replicate a working v1 use case with the newstyle commands.
