build error

[tinybug]

OS：macOS Sierra version: 10.12.3

I get this error:

gcc -g -O2    -o comskip comskip-comskip.o comskip-mpeg2dec.o comskip-platform.o comskip-video_out_dx.o ccextratorwin/comskip-608.o ccextratorwin/comskip-ccextractor.o ccextratorwin/comskip-encoding.o ccextratorwin/comskip-general_loop.o ccextratorwin/comskip-myth.o /usr/local/lib /usr/local/lib  -lpthread -lm 
ld: can't map file, errno=22 file '/usr/local/lib' for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Dose anyone meet this error? Thanks for your help!
