It depends on if you need 'eval' or object loading capability. For true plugins, hs-plugins is still the only binding to the GHC rts object loader, for eval-like mechanisms, we've a number of bindings to the ghc-api bytecode interpreter, such as hint. That said, hs-plugins is kinda sorta patches-applied maintained. jfredett:
I believe that hs-plugins has fallen out of use, on #haskell, I was directed to hint[1]. IIRC, I had to disable some packages because of cross installation.

Hi!
I was trying to install hs-plugins both from sources "$./Setup.lhs ..." and with "$cabal fetch&&cabal install" and both failed. It always reports that Linker.h is missing. I have tried to use --extra-include-dirs with path to ghc-6.10.1 dir and ghc-6.10.1/include dir. Nothing changed.
Here is a report from Setup.lhs:
Setup.lhs:2:2: Warning: In the use of `defaultUserHooks' (imported from Distribution.Simple): Deprecated: "Use simpleUserHooks or autoconfUserHooks, unless you need Cabal-1.2 compatibility in which case you must stick with defaultUserHooks" Warning: defaultUserHooks in Setup script is deprecated.

If the library is already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where it is.
