The problem with a plain pencil eraser is not in the eraser, but the
"lead" from the pencil. 

It's been a very long time since pencil leads were made from lead or
even of mostly graphite.  Nearly all pencil leads today are a mixture of
various clays, graphite, maybe a little lead, and who knows what.  

The oils in the clay are what cause the smearage. You need some sort of
solvent that will lift clay off of the surface.

Forgive me, I watch entirely too much PBS.

OK, I "experimented" a bit with a pencil, and some pre-moistened, 
alcohol-based screen cleanining
wipes (I'm using "One Step" from Read/Right) and with a little rubbing, 
the pencil mark came right off.

I also had some other wipes (Screen Guardian from Kensington) which 
didn't work as well (some of the mark came off, but too much of it was 
left behind, leaving a smeary mess no matter how much I rubbed....
