Problems building set for Beaglebone black.

[Travis Wheatley]

Working on a project for Beaglebone black. I have gone through the following set of steps to download and and subsequently run sb-set-builder:

$ mkdir -p development/rtems/sources
$ cd development/rtems/sources
$ git clone -b beagle https://github.com/bengras/rtems-source-builder.git
$ ./rtems-source-builder/source-builder/sb-check 
$ cd rtems-source-builder/rtems/
$ ../source-builder/sb-set-builder --log=beagle.txt --prefix=$HOME/development/rtems/4.12 devel/beagle.bset

After about a minute or so I get the following build error:

The above mentioned build report seems to indicate that the expat project that it is trying to download doesn’t exist.

Not sure what to do to correct this. Suggestions?
