PIL- error message- cannot open libtiff.so.3

[Tuvas]

Okay, so I've been getting this error message when trying to use PIL to
open a JPEG, that there isn't a library by the name of libtiff.so.3 .
I've been searching the documentation, there isn't any reference to
this library. Also, I don't know why it's doing this as I'm trying to
open a JPEG, and not a tiff. I tried with a .bmp with similar results.
Any ideas? Thanks!
