Setup wants to install 1.5.10 because 1.9f is "Exp".  The dependency
logic doesn't take into account version numbers at all, it's strictly
"package foo requires package bar", with no version information in the
equation.

If you want to keep one or more packages at "Exp" versions this is the
method I use:

First thing you do after running setup each time, switch to partial. 
You will see a combination of Exp packages that setup wants to downgrade
to Curr, mixed with any normal packages that you're not using Exp
versions of that need upgrading.  For all the packages that you are
using Exp versions, just toggle them back to Keep, and then continue
with setup as normal.  It's not very elegent, but most of the time
there's not more than a small number of Exp packages so it's pretty easy
just to switch them all back to Keep first thing.  After a couple of
times it becomes habit because it's the same packages each time.

Plan B is to use Exp versions of *everything*, in which case you just
use the Exp radio button each time.  But I wouldn't necessarily
recommend that.

(And yes, setup could be a lot more intuitive about all this... *sigh*)
