Chicken-and-egg problem installing Gem `guard-rack` 1.1

00-introduction.markdown

Ran into this while installing a new Ubuntu Server 12.04 image. Dozens of other Gems install fine, but... have a look at 01-dump.txt

System is:

• Ubuntu Server 12.04 (kernel 3.2.0-26-generic #41-Ubuntu) running under VMWare Fusion Version 4.1.3 (730298)
• 1 GB RAM, 20 GB HD, 2 CPU cores
• Ruby 1.9.3p0 (2011-10-30 revision 33570)
• gem version 1.8.11

File 01-terminal-output.bash is the terminal output from attempting to install the Gem using sudo gem install guard-rack

File 02-terminal-output-verbose.bash is the terminal output from attempting to install the Gem using sudo gem install guard-rack -v

Any assistance greatly appreciated.
