the repo will probably be choked with downloaders for days
should be, um, challenging, to get a usable build for the ov out of the aosp build system.
not that i'm a building expert, but all I've gotten to run from aosp lately is generic_armv5 (you can get to it with choosecombo or add a lunch product like generic_armv5-eng)
anything else I've tried so far produces unexecutable (on the ov, anyway) binaries.
maybe someone else will pin down a buildable device folder before I do... i'm currently trying to meld blarf's device_ and vendor_lge_thunderc with the generic_armv5 makefiles to produce something that'll run.
regardless of who does it first, hopefully they share so everyone can join in the fun.
