+* checking foreign function calls ... NOTE
+  Registration problem:
+  Evaluating ‘.ggobi.symbol(.name)’ during check gives error
+
+  This is a false positive - the package manually adds a prefix to
+  every C function name in order (I presume) to avoid conflicts. This
+  is no longer necessary but it would be a lot of work to fix.
+
+## Reverse dependencies
+
+I did not re-check the revdeps because this version just fixes R CMD check issues.
