The Haskell maintainers in Arch have an almost fantatic fascination with dynamic linking. Dynamic linking is otherwise not the norm in Haskell.

Haskell has poor support for dynamic linking. The Haskell (GHC) ABI is known to break on every compiler release. This means that every dynamically linked executable in the system needs to be recompiled. Any programs you compiled locally against dynamic system libs will break, of course.

This stance makes it much harder than necessarily for Arch users to get started with Haskell.
