You rarely need to import 'Internal' directly.

Are you sure this is not just a versioning problem? I.e. that some
library is built against bytestring-0.X.Y, but your current import is
bytestring-0.A.B, but your program expects these to be the same? (And
they probably are, but the compiler can't really tell).
If I haven't seen further, it is by standing in the footprints of giants
