I installed 1.9.1p129 a few weeks ago on Fedora Core 10-64 and the irb 
CL history is fine.  It almost certainly uses readline and probably 
would not build at all without it, but just in case: are you sure you 
installed the DEVELOPMENT libraries for GNU readline, which are required 
for source builds, and not just the normal library package, which is 
just objects for pre-built binaries to link to.

Ruby readline() is probably a red herring here.
