This is kind of a silly problem, but I'm trying to get phenix.rosetta_refine running on my computer and I am having some difficulty getting rosetta.build_phenix_interface to run. I'm getting a permission denied error in the 

os.symlink(python_lib, lib_link_name) line in rosetta_build_phenix_interface.py script

 and presumably I could fix this by changing the write permissions to wherever this points to, but I don't know where. 

Could anybody point me towards the folder that needs to fixed?

Thanks,

Dan
