I was looking for a way to include it in the output of the ruby 
benchmark suite so that the logs were more descriptive of which version 
of Ruby was being run :)

Currently I can glean this information from rbconfig:
Ruby VM: ruby [ruby 1.8.6 (2008-07-17 patchlevel 279) [i386-mingw32];-g 
-O2]

The -O2 is quite useful [don't want to compare versions that are 
compiled with different -O settings and call it fair]..  The version of 
GCC would also be useful for the same reason.
