Welcome to the Monastary!

Please review Writeup Formatting Tips for information on how to format your post properly.

Your post shows conflicting versions of ODBC:
unixODBC 2.3.1 vs
DBD::ODBC 1.31

You seem to be using ODBC version 1.31 which is from 2011.
The current version of DBD::ODBC on cpan is 1.56.

There is a comment on the fixes for ODBC version 1.34 that may be relevant to your issue:

1.34_3 2012-02-03
 
  [BUG FIXES]
 
  * Linking against unixODBC was working by accident on most UNIX
    machines and depended on the order of the files in /usr/lib (or
    wherever) and what files there were (e.g. an archive or a shared
    object). Same applied to iODBC but it was more broken especially
    on machines where libiodbc.so.N.N existed but there was no
    libiodbc.so which could lead to no adding the shared object at
    all. I doubt anyone really noticed this but I did eventually on
    Ubuntu where libiodbc.so.N.N existed but libiodbc.so did not.
Try installing a more current version of DBD::ODBC.
