Hi, Sandeep --

Note that Mountain Lion (OS X 10.8) and Mavericks (10.9) both 
still ship from Apple with very old revisions of iODBC, which 
lack patches necessary for each of these OS X versions.

Also -- even though Apple ships only the iODBC dylibs, they
recommend linkage to Frameworks, which are delivered (along
with the updated dylibs) by the precompiled SDKs mentioned 
below.

My immediate guess is that you have not installed the latest 
updates of the iODBC SDK (3.52.9, downloadable as source from
GitHub via iodbc.org --

   http://www.iodbc.org/dataspace/iodbc/wiki/iODBC/Downloads#Stable_Version_3529

-- or installable as precompiled binaries with any current driver 
from OpenLink Software, e.g., the Generic Client component of
our Multi-Tier solution --

http://download.openlinksw.com/components/6.3/universal-apple-macosx10.5-32/mvo3czzz.dmg


Is is also likely that you have not installed the environmental 
patch provided here --

   http://www.iodbc.org/dataspace/iodbc/wiki/iODBC/Downloads#Mac_OS_X

-- as iodbc-usr-sdk.zip --

   http://www.iodbc.org/downloads/iODBC/iodbc-usr-sdk.zip

On my own Mavericks machine, for instance, where I have installed
the latest iODBC *and* run the environmental patch, I have no 
/usr/bin/iodbc-config, but instead --

   $ /usr/local/iODBC/bin/iodbc-config --libs
   -L/usr/local/iODBC/lib  -liodbc -liodbcinst

I hope this is helpful.

Ted
