I haven't used profile.pl myself, but looking at the error, it looks 
like there's a run-time library (profile_rt.so) that it's looking for in 
/usr/local/lib but can't find.

I suspect that profile_rt.so is built as part of LLVM, but since you 
haven't done a "make install," profile_rt.so is still just sitting in 
the Release/lib (or Debug+Asserts/lib) directory.

If you search for profile_rt.so in your LLVM object tree and change the 
script to load it from that directory instead, the script may work for you.
