Probably version 4.1 --- I remember in the past always having to install the 
readline41-4.1-xx package to get R to work.  Perhaps Martyn should go back to 
linking against that in the short term until the bug in readline can be 
squashed?  Or does R-1.7.x need some additional functionality provided by 
readline-4.3?
