Trying to install cvxopt package using pip generates the following error message - how can I avoid this? Any other package also fails with same message:

raise ffiplatform.VerificationError(error)
cffi.ffiplatform.VerificationError: importing '//anaconda/lib/python2.7/site-packages/cryptography/_Cryptography_cffi_4ed9e37dx4000d087.so': dlopen(//anaconda/lib/python2.7/site-packages/cryptography/_Cryptography_cffi_4ed9e37dx4000d087.so, 2): Library not loaded: @loader_path/../../../libcrypto.1.0.0.dylib
