I am trying to build Ruby 1.9 on Mac OSX x86 Tiger. This first requires
an update to readline.
I have updated my readline but installed it to /usr/local since I do not
want to update the original binaries.
The problem is the configure script is trying to use the one in /usr/bin
and I don’t know how to tell it otherwise.
The option --with-readline-dir=/usr/local sprinkled all over the web
does nothing as there is no such option in the configure script
(specifically it leads to an unrecognized option warning). I have tried
3 of the different 1.9.x releases all with the same result.
