ghc 6.10.3 is NOT linked to libedit

[kazu-yamamoto (Kazu Yamamoto)]

ghc 6.10.3 depends on libedit but ghc 6.10.3 which I installed is not linked to libedit.

% otool -L /opt/local/lib/ghc-6.10.3/ghc           
/opt/local/lib/ghc-6.10.3/ghc:
	/opt/local/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
	/opt/local/lib/libncursesw.5.dylib (compatibility version 5.0.0, current version 5.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.4)
	/opt/local/lib/libgmp.3.dylib (compatibility version 9.0.0, current version 9.0.0)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)

Because of this, I cannot use command history of ghci (e.g. C-p). Note that I could use this feature on ghci 6.10.2.

[kazu-yamamoto (Kazu Yamamoto)]

I have resolved this problem. GHC starts using Haskeline instead of libedit. Since the default key binding of Haskeline does not provide C-p, this happens. Adding the following lines to your "~/.haskeline" binds C-p to the previous history command.

bind: ctrl-p up bind: ctrl-n down

Note that I guess dependency to libedit should be removed.

Yes, 6.10.3 no longer depends on libedit, but on the Haskeline. I will remove the dependency as part of other cleanups.

r53756 updates the dependencies.
