Installation on Mac OSX 0.12.4 (Sierra) fails due to missing LDFLAGS

[skoroneos]

Trying to install on Mac OSX from PIP or from source results in a linker error due to the missing path to OpenSSL.
cc -bundle -undefined dynamic_lookup -arch i386 -arch x86_64 -Wl,-F. build/temp.macosx-10.12-intel-2.7/src/mmapbitarray.o build/temp.macosx-10.12-intel-2.7/src/bloomfilter.o build/temp.macosx-10.12-intel-2.7/src/md5.o build/temp.macosx-10.12-intel-2.7/src/primetester.o build/temp.macosx-10.12-intel-2.7/src/MurmurHash3.o build/temp.macosx-10.12-intel-2.7/src/pybloomfilter.o -lcrypto -o build/lib.macosx-10.12-intel-2.7/pybloomfilter.so
ld: library not found for -lcrypto
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'cc' failed with exit status 1

After Setting the LDFLAGS in env it builds ok
i.e
sudo su
export LDFLAGS=-L/usr/local/opt/openssl/lib
