 MacPorts 1.8 introduced a new option to macports.conf: '''build_arch'''.  This allows you to control the architecture targeted by builds.  For example, you can use this to build 64bit on 10.5 (where 32bit is the default) or 32bit on 10.6 (where 64bit is usually the default).
 
+Another use case is when authoring a port on an Intel based Mac one can use the following command to do a checksum for arm64:
+{{{
+sudo port -d checksum <portname> build_arch=arm64
+}}}
+
 Documentation on this feature can be found in the man page for ''macports.conf'', and also in the Guide.
 
 There are two issues to note before you try and use build_arch:
