[geos-devel] Can't build geos with ruby swig bindings on Mac OS

[Ramie Blatt]

Hi Charlie,

After (a seemingly successful) build of geos-3.0.0rc4, I did cd to  
the both the "/usr/local/src/geos-3.0.0rc4/" build directory and the  
"/usr/local/lib/ruby/site_ruby/1.8/i686-darwin8.9.1/" directory  
(which contains the resulting geos.a, geos.la, and geos.so files) and  
try irb and got the "LoadError: no such file to load -- geos" error  
when I typed "require 'geos'" in the irb console.

I'm attaching a full terminal log of the rc4 build process and the  
irb sessions called "geos-3.0.0rc4_err.txt"

A partial trace for the make error on the geos-3.0.0rc1,2 and 3  
tarballs is below. and I attach a full terminal log for the build  
process on rc3 called "geos-3.0.0rc3_err.txt".

Many thanks for your help!
