Dear all, I downloaded the GHC 6.6 tarballs, built and installed them on my mac (Tiger, PPC) using the documented procedure: ./configure make make install The build and install was fairly smooth. However, ghci will not recognize "control characters", e.g. delete/backspace, arrow keys, ctrl-a, ctrl-d et c. It seems to recognize ctrl-c for cancelling a line but will print the ^C first. A typical session may look like: ___ ___ _ / _ \ /\ /\/ __(_) / /_\// /_/ / / | | GHC Interactive, version 6.6, for Haskell 98. / /_\\/ __ / /___| | http://www.haskell.org/ghc/ \____/\/ /_/\____/|_| Type :? for help.

My previous installation of GHC (6.4.2 from darwinports) didn't have these problems. I realize that this may be due to my lack of unix skills rather than pertinent to GHC. Any help would be appreciated. Thanks, Bjorn Buckwalter
