Report each file download as it is attempted

download binaries to specific directory

Note requirement for recompile functionality
Try a different appraoch to configure Bundler via env variable
inspect environment variables in process before bundler
Correct ruby bug
inspect environment contents of geo binary directories
Try accessing libraries at relative paths
Try accessing libraries at absolute paths using pwd
Try a syntax change to address bug
Set include directories vs lib for rgeo binaries
Try parent of lib and include :p
Add geos libs to path for runtime access
Fix stupid bug
