Looks like a mismatch in readline library versions.  You installed GHC
from the binary distribution, which doesn't check that you have the
right readline library version installed.

What libreadlines are floating around on your system?  Have you done any
local hacks such as symbolinc-linking libreadline.so.3 to
libreadline.so.4?
