G'day Joey. Trying to deploy to a new host and I'm hitting this error:

When I build propellor manually on the remote host, same issue:

/usr/local/propellor# cabal build propellor-config
cabal: Unrecognised flags: propellor-config

Building without the propellor-config flag appears to work fine:

/usr/local/propellor# cabal build
Building propellor-3.0.4...

...
Linking dist/build/propellor-config/propellor-config ...
Preprocessing executable 'propellor' for propellor-3.0.4...

So when I change line 39 in Bootstrap.hs to drop "propellor-config" it appears to work OK, locally:

% ~/.propellor/propellor --spin os01.mcwhirter.io

However it still fails with the original error on the remote host, despite the new Bootstrap.hs having been copied in place correctly.

I feel like I'm working around another local issue but so far my "fix" has been in Bootstrap.hs.

Thoughts?
