mkdir: ./bin/out_no_gpu: Permission denied

[cmot17]

I have been trying to get VisualSFM to compile for a while. I managed to fix a bunch of errors bye poking around here but I cannot fix this one with libPBA.
Here is the error I get:
Changing SiftGPU GCC to Brews gcc-4.9 Removing /usr/lib64 from makefile Changing march from native core2 in makefile Adding -L/usr/include/sys/ to compile Flags usage: cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file target_file cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file ... target_directory /Users mkdir -p ./bin/out_no_gpu mkdir: ./bin/out_no_gpu: Permission denied make: *** [makepath] Error 1 libpba.so failed to build, halting.

Any help will be appreciated.
Thanks!
