The new MacOS Ventura seems to have broken gfortran MacOS version control. To reproduce my error you only have to do
gfortran --version
And the output is
gfortran: warning: could not understand version ‘13.00.00’
GNU Fortran (GCC) 11.3.0

This in itself is just a warning so it might not be a big deal but it breaks "./configure" scripts that require some MacOS versions, e.g. if you try to compile LoopTools you get the following error (in the log file)
arm64-apple-darwin20.0.0-gfortran: warning: could not understand version '13.00.00'
ld: -rpath can only be used when targeting Mac OS X 10.5 or later
collect2: error: ld returned 1 exit status
Since the version cannot be properly read it cannot be compared.
Is there some sort of work around this bug?
I had installed gfortran through conda but aparantly the version is from last year.
I solved it by removing it from conda (had to remove conda entirely due to linking issues) and installed it with brew : brew install gcc.
