Install fail on OSX 12.6.2

[toddr]

The relevant Configure output seems to be:

Use which C compiler? [clang]  
clang: error: invalid arch name '-arch -mmacosx-version-min=12.6'
clang: error: invalid arch name '-arch try.c'
clang: error: no input files
Uh-oh, the C compiler 'clang' doesn't seem to be working.

Is there a way I can specify my arch?
