I'm trying to install Distance for python on my mac (OS X Yosemite).
After downloading the package and unpacking it, I run (as described on their page):
python setup.py install --with-c
From this I get the following error message:
running build_ext
building 'distance.cdistance' extension

ld: library not found for -lgcc_s.10.5
clang: error: linker command failed with exit code 1 (use -v to see invocation)

From what I understood from several posts like this one or this previously asked question, it looks like clang, which is called through the command gcc, can't find the libgcc library.
I ran find /usr/ -name libgcc*and this if what I get:
/usr//lib/libgcc_s.1.dylib

/usr//local/gfortran/lib/libgcc_s_x86_64.1.dylib
And now I'm stuck because I don't know what to do next. Basically the question is: how do I make clang to know where the library is ?
