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

Hmm - that file is generated by the makefiles during ./configure.  If it 
doesn't exist, then you couldn't have built the capi library either.

  After I remedied that, it

I'm not very familiar with Mac OS.  But it seems me there are 2 
possibilities. First, the error message is correct and Ruby can't find 
geos.so (the bindings).  Verify Ruby's load path is correct.

The other possibility is that Ruby is finding the geos.so (the bindings) 
but can't find the geos_c.so (the c library).  Does OS X have dependency 
checker of some sort so you can tell if that's the issue?

It sounds like you've built the Ruby bindings just fine.  I don't think 
that's the issue here.  It sounds much more like a load path issue.  I 
assume you did a make install on the geos c library?  I assume you've 
set various permissions correctly?  Etc.
