Kitchen build errors (user.hv & default.hv)

[SweetBearCub]

I tried to build a ROM this morning and it terminated with an error message referring to user.hv and default.hv.

I think it mat have been caused by something I added (or didn't add) in the kitchen, but I don't know what.

I have not added any of my own packages, I only used what was included in the kitchen itself.

My Build Log file is attached to this post.

Also, a couple more questions:

1) Why can't I select "Battery & Performance Tweaks" in the kitchen? I tried, but it will not accept a checkmark.

2) WMWiFiRouter. The kitchen includes a trial copy of a 1.xx release. I have v0.91 (the last free version) and would like to continue using it. Why is it not included?

Thanks!
