I worked on this for a while.
Long story short. You need to dedicate about 1-2G of your Z's internal storage to hold all the files for portage.
Emerge sync took 5 hours the first time. Compiling anything is painfully slow.
Eventually I ran into the situation where after struggling for weeks to properly update portage and the OS, portage just flat out broke. I was unable to reinstall portage because there is no arm based distribution. Also, there is no arm profile in portage, so whe you do update it gets removed.
This is why I'm using pdaxrom now.

Yeap, I think use pdaXrom is Better too!
Gentoo only for tests because compile a entire system in a PDA is .... no cense
