Haskell ghci command line. return value overwrite last prompt

I installed ghci on Max OSX.

But everytime, the return value overwrite my last ghci prompt. See below.

Falseghci>null[1,2,3]
Luke_ghci>

"False" over write my last line ghci prompt. (should be Luke_ghci)

So weird. How to solve it? Thanks.

Copied from the above-linked message:

Aha! That led me to find it: I had TERM set to 'ansi'. ghci + Haskeline works find if TERM is set to any of rxvt, vt52, vt100, vt102 or xterm. Don't know what in terminfo Haskeline is relying on, but 'ansi' doesn't have it!
