Cabal doesn't pass the --main-is option, I believe because it is specific to GHC. What you could do is add this flag in the ghc-options field of your executable in the cabal file, like this:
ghc-options: --main-is Shell
That worked like charm, except the two dashes should be one (my mistake). Thank you.
Note that hackage will reject packages that use "ghc-options: -main-is" with the message that it is not portable. The rationale is that unlike other non-portable extensions, it is easy to change to make it portable: http://hackage.haskell.org/trac/hackage/ticket/179 If you want to argue for supporting this ghc extension and/or implement support (possibly with workaround support for the other haskell implementations) then please do comment on the above ticket.
