Duplicate SafeMath in Solidity libraries

I'm working on a Solidity smart contract, and I'm importing both the openzeppelin-solidity library, as well as the chainlink library.

Both have the SafeMath library; I'm loading all the .sol files in Python. When I try to compile (Python), I get the following error:

TypeError: Member "div" not unique after argument-dependent lookup in uint256

I got this error the moment I added the chainlink library, so I guess the problem is the duplicate SafeMath definition? Obviously I don't want to go change imports in either library.

How best to solve this?

Chainlink repo now uses safeMathChainlink to avoid naming conflicts, so if you import that you’ll not have those issues.

Also, in v0.8 of solidity, safeMath as a whole is no longer needed
