+# a crutch to get us by until a proper solution is implemented in base.
+# See #20728.
+# 
+# Usage:
+# 
+#   PortGroup               archcheck 1.0
+#   archcheck.files         file1 file2 ...
+#
+# Files can (and probably usually should) be specified relative to ${prefix}.
+
+options archcheck.files
+default archcheck.files {}
+

+        set requested_archs ${universal_archs}
+    } else {
+        set requested_archs ${build_arch}
+    }
+    foreach file ${archcheck.files} {
+        # Prepend prefix if necessary.
+        if {"/" != [string index ${file} 0]} {
+            set file [file join ${prefix} ${file}]
+        }
+        set file_archs " [strsed [exec lipo -info ${file}] {s/.*://}] "
+        foreach requested_arch ${requested_archs} {
+            if {-1 == [string first " ${requested_arch} " ${file_archs}]} {
+                ui_error "You cannot install ${name} for the architecture(s) ${requested_archs}\nbecause ${file} does not contain the architecture ${requested_arch}.\nYou may want to rebuild the port that provides that file using the universal variant."
+                return -code error "incompatible architectures in dependencies"
+            }
