Re: fresh checkout and compile

[Ryan Mitchell <remitche@indiana.edu>]

Hi Mark,

Thanks for looking at this.  I see the chicken and egg problem.  Of  
course having all this done automatically (or having the HDDM and HDDS  
packages separated out) would be ideal, but having the user take a few  
extra steps isn't absolutely terrible either, as long as its  
documented, imo.

Thanks,
Ryan
