Revision bump ragel to fix the generated state machines to work with Ruby 1.9. Also fix both the new and old (stable) ebuild to run econf just once, as it was broken when adding prefix support.

+Subject: [PATCH] Fix generated code for Ruby 1.9 compatibility.
+
+In Ruby 1.9, the String class no longer works as a C-style array of (8-bit)
+characters, but supports multiple encoding. While it is obviously a task
+for the developer to ensure that the data array passed to the
+Ragel-generated code is in a compatible encoding, this also means that the
+simple dereference is not going to work:
+
+% ruby18 -e 'puts "foo"[0].class'
+Fixnum
+% ruby19 -e 'puts "foo"[0].class'
+String
+
+This is easily fixed by calling the #ord method on the dereferenced data,
+which will provide the ASCII ordinal (or UNICODE codepoint) for the single
+character.
+
+The produced code works correctly both on Ruby 1.8 and 1.9.2.
