I have had the same problems (using ODBC/MySQL on SID). The old unixodbc version looked into /etc/odbc.ini first, the new one into ~/.odbc.ini. Please check that.
If using isql, try isql with -v. You should get a more verbose error message. In my case, I had a 'UserName = blabla' within my DSN section inside .odbc.ini. The new unixodbc version seems not to understand this and set the database user to 'dummy'. After changing this to 'User = blabla' everything worked correctly (so far, I discovered all this a few minutes ago). Hope it helps.
