Charm++ parallel programming system

[Tom Quinn <trq AT astro.washington.edu>]

I figured out the problem: there was a left-over CkLoop.decl.h and 
CkLoop.def.h in the src/libs/ck-libs/ckloop directory.  These got linked 
over into the build directory instead of being regenerated.  Thanks for 
the help.
