[Rd] How to compile R with command completion?

[Simon Urbanek]

Peng,

as you can see there is no -lreadline so I'd look further up in  
config.log to see why it's failing -- do you have LD_LIBRARY_PATH  
setup to match your custom location of libs? (Also I notice you are  
building x86_64 yet the readline you are showing is in /lib and not  
in /lib64 -- did you build it just in 32-bit?)

Cheers,
Simon
