Pothos Blocks fails to compile Mac Big Sur

[keesL]

Hello all,

While following the build instructions on https://github.com/pothosware/homebrew-pothos/wiki, I failed to build Pothos Blocks on MacOS Big Sur. To make sure, I used a blank brew environment.

brew install pothosblocks

fails with the following errors

I made a new release tag that should have the fixes: https://github.com/pothosware/homebrew-pothos/commit/c4c12ff16d6d0618f73adf3a90f1f9acae5f6a02

I have more tags to make for other projects to come :-)

Confirmed fixed. Thank you!
