Ok, I ll give it a try for rebuilding it from scratch . I found that my r=
uby-install was old and maybe some flag need to be adjusted (and was mayb=
e done already in latest version)

By the way, I am running Xubuntu 12.04 on a VM, latest of  ruby-install a=
nd chruby  now and will let you know what  I found.

Also I was looking at the code where I can only see one place in kgio ref=
erring to method_defined?

if (!rb_funcall(cFile, rb_intern("method_defined?"), 1,
                        ID2SYM(id_to_path)))
                rb_define_alias(cFile, "to_path", "path=E2=80=9D);

thanks

Emmanuel
