OK.  I may see if I can just get it to compile by changing the few 
'underscore' errors that show up.  But I will seriously consider the 
virtualbox.  One thing that bothers me is having to limit the RAM 
accessible by the virtualbox (this would impact dolfin if I were computing 
something big).

Actually, could I just run a virtual terminal on my windows PC that 
connects to some other linux box?  Orginally, I wanted to avoid this 
because I was unix retarded.  However, in the process of mucking with all 
this compiling, I am now less retarded.  Is this a viable option?
