332 introduced Lift instances. However, this uses the TemplateHaskellQuotes extension, which is only available since GHC 8.0. There are several options how to resolve this:
drop 7.10 support
use the TemplateHaskell extension for 7.10
don't define the Lift instances for 7.10
EDIT: The Lift instances also use emptyArray#/emptySmallArray#, which isn't available either for GHC 7.10.
