You won't be able to do a straight source build from 6.4 to 9.1; too many
low-level changes like Makefile syntax and compiler options have changed. 
If you are comfortable with temporarily disabling non-essential things that
fail to build, it is definitely possible to do a long jump to 9.1, but it'd
be safer to either hop from 6.4 -> (7-stable or 8-stable) -> 9 doing
buildkernels and buildworlds, or just do a binary upgrade of kernel and base
system to 9.1.
