well, it's quite strange: you seem to be getting an _incomplete_ readline 
import.  You may want to look inside the readline directory and see if the 
code looks OK, and/or put a few print statements inside there, to see why it's 
not building a complete module.

Check for issues with ctypes imports inside readline and too-eager try/except 
blocks which may be trapping an error and silencing it.

Very strange.

Cheers,

f
