Error during event generation in macOS

Not sure what to say here.

Your gfortran seems to have been installed for an older version of OSX, so maybe this is the issue.
Since the error is an issue with the detection of your OS.

You also seem to have custom ways to compile the code
(in particular, the problematic compilation flag
> -Wl,-rpath,/Users/surrutiaquir/Software/Python/envs/PHY/lib -L/Users/surrutiaquir/Software/Python/envs/PHY/lib
is not something that "we" do inject, so those flag are induced by your environment.
So maybe a solution is to remove those flag from your environment when compiling madgraph.

Cheers,

Olivier
