I have successfully built Ruby for 64 bits under AIX,
the only thing I had to do was to persuade the compiler to
compile for 64 bits.

Under AIX, there is a simple way: I just defined the environment
variable OBJECT_MODE=64.

You must look at the documentation of your C-compiler to find out
how to do this. (Of course, you must do it before running the
configure script.)
The only problem I experienced was that the configure script
added -I/usr/local/include to the compilation flags. This lead to
hard to detect obsure errors, because the 64 platform needed its
own header files and this was overriden by this setting.
I had to prevent confifure from doing this, but I am not sure
whether you would need such tricks.
