Well, we've never shipped a version number 2.1.9.5, so that tells me you're 
probably using a binary packaged version provided by some other source. 
Maybe your OS vendor, maybe someone else.

However, since we don't know what they may have done to the code that they 
have packaged and shipped to you, we can't really tell you anything about 
how things may now act if you've applied some sort of patch or something 
from our code to try to bring you up to date.

If you want to completely de-install the old version and then re-install 
from our tarball, I would expect that should work, but I won't give you any 
guarantees.


Your first step for resolving all these problems should be to contact your 
vendor who provided the previous binary package version you were using, and 
get assistance from them.
