I did a quick conversion from perl to ruby:

#!/usr/local/bin/ruby

infile = ARGV[0]

out = File.open("cs.c", "w")
out.puts <<"EOF"

#include "ruby.h"
#include <stdio.h>
#include <string.h>

char key='\xFE';
EOF

out.print 'char unenc[] = { "'
File.open(infile).each_byte do |c|
 out.printf("\\x%x",(c^254))
end

out.puts <<"EOF"
"};

int main(void) {
    ruby_init();
    ruby_script("crypted");
    crypt(unenc);
    //printf("%s",unenc);
    rb_eval_string(unenc);
    return 0;
}

int crypt(char *u1) {
    while(*u1) *u1++ ^= key;
    return 0;
}

EOF
out.close

system("gcc -lruby -I/usr/lib/ruby/1.6/i386-linux/ -o cs cs.c");

I haven't tested it except for a diff between the output which showed
no difference.
