I am trying to compile ruby 1.8.7-p17 on my Macbook where I have  
readline 5.2.012 installed via MacPorts and the compile fails with the  
following error:

readline.c: In function ‘filename\_completion\_proc\_call’:  
readline.c:703: error: ‘filename\_completion\_function’ undeclared (first  
use in this function)

A detailed (configure/make) log is attached… Any ideas? 1.8.6-p114  
compiled fine this morning on the same machine…

Thanks!

Never mind… sorted it out by adding --with-readline-dir=/usr/local to  
the configure args… Apparently ruby 1.8.7 is not compatible with  
Apple’s bundled readline.
