In order to install memsql-python you need to ensure that you have the dependencies already available. Specifically, the dependency that seems to be missing from your environment is libmysqlclient-dev or an equivalent package.

Note - you are overriding the include paths to point at your openssl installation which may be causing this issue due to how the compiler is searching for development headers.

According to the project's readme, use the following steps to get started quickly on Ubuntu:

sudo apt-get update
sudo apt-get install -y mysql-client python-dev libmysqlclient-dev python-pip
sudo pip install memsql

Use the following steps to get started with RHEL based distributions such as Amazon Linux or Centos:

sudo yum update
sudo yum install -y gcc mysql-devel
sudo pip install memsql

-- edit to address question regarding installation on Mac OSX On a Mac it appears that you can install the mysql-client package from brew which in theory should provide the libmysqlclient-dev package. Once available try installing the memsql-python package without overriding linker flags since memsql-python should build fine without openssl. If you need openssl support then you will need to ensure that both the openssl and libmysqlclient-dev shared objects are available to the linker at compilation time.
