Subject: Issue installing Watir (and other Gems) on Windows

Hi, completely new to Ruby, which I'm using to try out Watir. I seem to
be having issues installing Watir (and other Gems in general). Got as
far as figuring out where the mkmf.log file is located, and it contains
this:

package configuration for libffi is not found
"x86_64-w64-mingw32-gcc -o conftest.exe
-IC:/Ruby/include/ruby-2.0.0/x64-mingw32
-IC:/Ruby/include/ruby-2.0.0/ruby/backward -IC:/Ruby/include/ruby-2.0.0
-I. -DFD_SETSIZE=2048 -D_WIN32_WINNT=0x0501 -D_FILE_OFFSET_BITS=64   -O3
-fno-omit-frame-pointer -fno-fast-math -g -Wall -Wextra
-Wno-unused-parameter -Wno-parentheses -Wno-long-long
-Wno-missing-field-initializers -Wunused-variable -Wpointer-arith
-Wwrite-strings -Wdeclaration-after-statement
-Wimplicit-function-declaration conftest.c  -L. -LC:/Ruby/lib -L.
-lx64-msvcrt-ruby200  -lshell32 -lws2_32 -limagehlp -lshlwapi  "
checked program was:
/* begin */
1: #include "ruby.h"
2:
3: #include <winsock2.h>
4: #include <windows.h>
5: int main(int argc, char **argv)
6: {
7:   return 0;
8: }
/* end */

Can anyone assist me with fixing this, what to check, etc?

Ruby is installed at C:\Ruby, and the development kit is installed at
C:\Devkit

Thanks!
