I got iowa working under ruby 1.7.3, but I had to make some small
changes.  Two changes were minor and only served to remove warnings, but
one of the changes (the one in Context.rb) was essential for
oid-generated links to work.

Here are my patches:

  			codedata = codefile.read
  		rescue Exception
