4.5 error: You don't have a working Tex binary installed, but the texi2dvi script can't proceed without it.

solution: sudo apt-get install texlive

4.6 error: failded to stat /home/danny/.gvfs: Permission denied

solution: Even though flagged as an error, these messages are harmless warnings that can be safely ignored. Before the RPM tool starts to install a package,

it checks if there is sufficient space for it in the file system. Unfortunately it is dumb and checks all mounted file systems for space, but the permissions of the ".gvfs" directory (the mount point for the Gnome Virtual File System) do not permit this.

4.7 error: md5sum mismatch, re-naming /opt/freescale

solution: apt-get install mtd-utils

4.8 error: can't get: mtd-utils-1.5.0.tar.gz

download "mtd-utils-201006.tar.bz2" from https://community.freescale.com/thread/384010
change it into "mtd-utils-1.5.0.tar.gz" which is required in 2 steps:

decompress: tar jxcf mtd-utils-201006.tar.bz2

compress: tar zcvf mtd-utils-1.5.0.tar.gz mtd-utils/
