ca-certificates update error on OS X 10.9.2

[jianglai]

I encountered this problem when doing a deep world upgrade.

It seems to have to do with this:

unpack nss-3.14.1-add_spi+cacerts_ca_certs.patch: file format not recognized. Ignoring.
mkdir: cannot create directory ‘image//Gentoo’: No such file or directory

Any help is appreciated!
