Well, actuaclly on os x it's named libncurses.5.0.3.dylib, but the 
version and compat versions are 6.x only if built with libtool. The 
problem is that libs with a version of 0 are generally a BadThing on OS 
X, and they made a general solution of adding 1 to both the version and 
compatibility version. I don't think many people other than myself (and 
the fink project) use libtool to build it, since it isn't the default 
to do so. I see a problem though, where people may build it with 
libtool/using fink, and then get pre-made binaries that are linked 
against ncurses built without libtool, and because it's a lower ABI in 
the app than the lib, it will refuse to work. I tried 
- --with-abi-version=4 in the configure line, to have libtool add 1 and 
make it 5, but that didn't work, the libs still had an ABI of 6.0.0.
