[DRE-maint] Bug#680227: webgen0.5: webgen does not work with default YAML implementation of ruby1.9

[Sebastian Reichel]

Package: webgen0.5
Version: 0.5.14+dfsg1-2
Severity: important

Hi,

in ruby1.9.2 the default YAML parser has been changed from syck to
psych. The new parser does not work correctly with webgen:

/usr/lib/ruby/1.9.1/psych.rb:203:in `parse': (<unknown>): did not find expected
alphabetic or numeric character while scanning an alias at line 8 column 11
(Psych::SyntaxError)
	from /usr/lib/ruby/1.9.1/psych.rb:203:in `parse_stream'
	from /usr/lib/ruby/1.9.1/psych.rb:151:in `parse'
	from /usr/lib/ruby/1.9.1/psych.rb:127:in `load'
	from /usr/lib/ruby/vendor_ruby/webgen/website.rb:358:in `read_config_file'
	from /usr/lib/ruby/vendor_ruby/webgen/website.rb:258:in `block in init'
	from /usr/lib/ruby/vendor_ruby/webgen/website.rb:316:in `execute_in_env'
	from /usr/lib/ruby/vendor_ruby/webgen/website.rb:252:in `init'
	from /usr/lib/ruby/vendor_ruby/webgen/website.rb:271:in `block in render'
	from /usr/lib/ruby/vendor_ruby/webgen/website.rb:316:in `execute_in_env'
	from /usr/lib/ruby/vendor_ruby/webgen/website.rb:270:in `render'
	from /usr/lib/ruby/vendor_ruby/webgen/cli/run_command.rb:17:in `execute'
	from /usr/lib/ruby/vendor_ruby/cmdparse2.rb:464:in `parse'
	from /usr/lib/ruby/vendor_ruby/webgen/cli.rb:124:in `parse'
	from /usr/bin/webgen:7:in `<main>'

Since the default ruby implementation has been changed from ruby1.8 to
ruby1.9.1 in wheezy, webgen is broken by default. The solution is to
switch back to the old implementation [0]. This can be done by adding

require 'syck'

as first code line of /usr/bin/webgen0.5
