Windows 8 64 bit ruby-debug-ide install of linecache19 failing due to gcc
-m64 flag error: sorry, unimplemented: 64-bit mode not compiled...

I am going through the install for windows per Is ruby-debug-ide available
to be installed on windows with ruby1.9.3? downloaded the gems and begin
to install them. But get this 64 bit error. Is there a 32 bit version of
linecache19. Do I need a different gcc compiler?
