 Well, strange you should ask... 

 Here's a shell script I hacked up for 2.1.6, which I have been told works
for 2.1.7.  With some slight modifications (check it against the makefiles
in /usr/src/release) it could possibly work for 2.2.x.  The script assumes
you have /stand on your local machine from the 2.2.1 install (it picks
that up instead of rebuilding it.)

 Also, just to offer words of encouragement - I _know_ how frustrating
this can be (just look at some of my other mail for examples :-) )  However,
when all is said-and-done, this is a deterministic environment.  There
answer _is_ there...
