I went ahead and installed the readline library but I can’t get ruby to recognize it. I rebuilt ruby, reinstalled gems, etc. What am I missing? -Doug ---

Make sure you have the readline headers installed - for some odd reason most Linuxes keep them in a separate package (‘readline-devel’ or something usually). Then go into the ext/readline subdirectory in the ruby source tree and make it manually. ---

I called configure so: ./configure --with-readline-dir=/usr/local Ruby is still refusing to believe I have: /usr/local/lib/libreadline.so /usr/local/include/readline/readline.h By the way I just realized I already had: /usr/lib/libreadline.so /usr/include/readline/readline.h What more need I do? -Doug
