Helpful information:
 * Contents of  /etc/make.conf
 * Contents of /etc/src.conf
 * More of the error message (that shows what it was trying to compile).  Usually the previous 20 lines or so are sufficient.

No, cross-compiling FreeBSD/ARM does not require these ports at all.
These ports are needed only if you are cross-compiling other software
manually.  The FreeBSD source tree has the necessary tool support
already built in.
