debugger fails to compile on fresh rbenv ruby 2.0.0-p0

[jgeiger]

I've got a fresh copy of ruby 2.0.0-p0 installed using rbenv. rbenv was installed using the basic github checkout method and the ruby-build was installed as a plugin to rbenv.

$ gem list
*** LOCAL GEMS ***
bigdecimal (1.2.0)
bundler (1.3.0.pre.8)
columnize (0.3.6)
debugger-linecache (1.1.2)
debugger-ruby_core_source (1.2.0)
io-console (0.4.2)
json (1.7.7)
minitest (4.6.1, 4.3.2)
pg (0.14.1)
psych (2.0.0)
rake (10.0.3, 0.9.6)
rdoc (4.0.0)
test-unit (2.5.4, 2.0.0.0)

When I attempt to install debugger I get the failure log below.

$ gem install debugger
