Comment (by rwbarton):

 > The dynamic linker must look in nearly 25 Haskell library directories to
 locate every system library! This is madness.

 Not only that, but just to spell it all out explicitly,

 * The dynamic linker has to look in those nearly 25 Haskell library
 directories for each Haskell library, too, making the behavior quadratic
 in the number of Haskell packages.

 * This applies not just to `ghc` itself, but to any executable that uses
 dynamic Haskell libraries. Some people have programs that use hundreds of
 different Haskell packages.
