thanks for the report. What dh_haskell_shlibdeps does is: It builds a
Haskell binary using the library in question (e.g. haskell-url) and
checks which libraries it links against. So if the user wants to use
haskell-url, he needs to have these libraries installed. In that sense,
the dependencies are not wrong.

But I guess you are arguing that they are inappropriate, as it is not
haskell-url that pulls them in, and redundant, because ghc already
depends on these libraries.

What if dh_haskell_shlibdeps compares the libraries required to build a
program with haskell-url with the list when building without, and only
adds these?

But is there really a problem you are trying to solve, or is it more or
less just cosmetics?

Greetings,
Joachim
