Raa-install --showall doesn't work

Here’s what I get:

$ raa-install --showall
Downloading project data
http://narf-lib.sourceforge.net/raa/raa-xml-compacted.xml
…/usr/bin/raa-install:50:
undefined method url' for #<RAAInstall::Package:0x40324490> (NameError) from /usr/bin/raa-install:49:ineach’
from /usr/bin/raa-install:49

$ ruby -v
ruby 1.6.7 (2002-03-01) [i686-linux-gnu]

I think it’s the latest raa-install.
