Here's a quick fix.

In the Rakefile:

desc "Generates the C scanner code with Ragel." task :ragel => [:ragel_version] do

puts @ragel_v.inspect if @ragel_v < 6.0

sh %{ragel ext/hpricot_scan/hpricot_scan.rl | #{@ragel_v >= 5.18 ? 'rlgen-cd' : 'rlcodegen'} -G2 -o ext/hpricot_scan/hpricot_scan.c}

else

sh %{ragel -I. -G2 ext/hpricot_scan/hpricot_scan.rl -o ext/hpricot_scan/hpricot_scan.c}

end

end

In ext/hpricot_scan/hpricot_scan.rl add a few variabls ts, te, and eof VALUE hpricot_scan(VALUE self, VALUE port) {

int cs, act, have = 0, nread = 0, curline = 1, text = 0; char *tokstart = 0, *tokend = 0, *buf = NULL; char *ts, *te, *eof;
