It would only be a single shared library.



Finally got the code publicly available:
https://github.com/markisaa/presto-odbc/blob/osxCompile/driver/driver.d#L61

It should compile on OSX with a simple `make clean all`
Testing would require installing the iODBC driver manager and
pressing the 'Add Driver' button, possibly making a new User DSN,
and possibly pressing 'Test'.
