The FiniteMap module from package 'data' is now available as
Data.FiniteMap from package 'base' (there's no need to explicitly
request 'base', it's always available).

This is a problem that will be fixed in the next release.  For now, just
omit the dependency.

The error is self-explanatory: it can't find libHSdocon.a on the path
given in the package specification.  It looks like you might have some
extra quotation marks in there.

Also, I wouldn't put '-package data' in extra_ghc_opts.  I think that is
unlikely to work.
