nithin not a wine issue. Ubuntu package issue. ln -s should work around if the so exists where the config says it is. [unixODBC][Driver Manager] ie is a native non wine message. But check if there is a package update first. Since the maintainer ubuntu freetdsof for this error to be happening has to have screwed up and not correctly tested packages before shipping. Yes a lot of Ubuntu maintainers need a swift kick up ass for basic mistakes of not building and running the testsuites to make sure their packages work.
