I tried with the Mac OS X and I would have some feedback...
- the iODBC library is contained in the Essential package (libiodbc.dylib);
- Essential package contains pkgconfig file (int /usr/lib/pkgconfig)
but not pkg-config script;
- Xcode does not contain pkg-config either;
- Apple removed isql.h and other iODBC include files from Xcode MacOSX
10.8 include directory. Also they removed iodbc-config. Did they
decide to deprecate iODBC?
- I installed iODBC PKG from iODBC website. The isql.h include try to
include a <iODBC/sql.h> as isql.h is not supported anymore however
there is no iODBC directory/link which contains a sql.h so the include
fails!

Looks like they are trying to make thing much harder for developers :-(

Not counting that my PKG database has still Xcode MacOSX 10.8 files
but files are not present anymore.
