I don't think anything can keep you from doing this transition, since
exts will never be portable across 32/64 or MRI/Rubinius or
1.8/1.9/2.0 C API...it kinda just has to happen if there's going to be
support for multiple installed Rubies on a single system.

I did not see you mention different locations for 1.8 versus 1.9
versus 2.0 exts...they are also not generally portable.
