Hello, I was trying to install monet on Mac OS 10.5 with monetdb-install.sh --enable-xquery --enable-optimize --nightly=stable It has always worked, but this time, it stops due to an error while configuring MonetDB: checking readline/readline.h usability... yes checking readline/readline.h presence... yes checking for readline/readline.h... yes checking for readline in -lreadline... yes checking for rl_completion_matches in -lreadline... no checking whether rl_completion_func_t exists... configure: error: readline/readline.h does not contain rl_completion_func_t, is it GNU readline? The complete log is in the attachment. What is wrong with my readline.h? How can I find out which readline.h the install script is checking, and which readline.h is expected / should be used? Thanks in advance. Jennie
