Comment (by thomie):

 You're right!

 curl's cabal file would still contain `extra-libraries: curl`. But when
 installing curl, whoever decides the parameters for the ghc-pkg file
 (either cabal or ghc, I don't know at the moment) could ask the linker
 which version it actually found, and write `extra-libraries:
 :libcurl.so.<version>` to the ghc-pkg file.

 That should work (at least on linux).
