ROMs Custom ROM Build to unstable and without NFC Settings

[Markus Taubek]

Hello,
I built a ROM from Branch gingerbread and one from master.
In both cases the NFC setting in "Settings > Network & Wirless > NFC" doesnt Exists.
Then I used to activate WLAN and the system hangs up.

Anyone has an idea why the setting is not exist?

Maybe I should get the source from a TAG and not from HEAD?

How I can get the Source from a TAG like -b gingerbread

I need a stable Android Version for my Nexus S to build up.

maybe somebody heave some helpful infos for me?
greets
Markus
