FreeBSD host ld can handle linker scripts fine, it is INSERT BEFORE .data;
which is not supported. Boards don't use the host linker script, but one for
the target, which comes from ports and hence is not that old e.g.

arm-gnueabi-freebsd-ld --version
GNU ld (GNU Binutils) 2.25

This program is free software; you may redistribute it under the terms of

Besides that, boards don't use INSERT before .data, since they have a 
complete
linker script.

FreeBSD ld has this option, it does not work on a MAC/Darwin though
according to Andreas his post. The problem on FreeBSD is the INSERT 
before .data
inside the "addendum" aka tools/imagetool.lds

pkg replaced the pkg_add / pkg_info and friends. So it is fine that they
are not there. The weird thing is I just booted 10.1 in virtualbox to 
reproduce
this but works fine (just defaults everywhere), I roughly did [1]. 
Obviously you
need root credentials to install packages, but I doubt you forgot that.

If this still fails, you can always build it from source, but needs a 
bit of patience.
Somthing like this should always work:

portsnap fetch
portsnap extract

cd /usr/ports/devel/git
make config-recursive
make
make install

Let me know if you still have issues.

Jeroen
