+      Your default Python does not recognize the Homebrew site-packages
+      directory as a special site-packages directory, which means that .pth
+      files will not be followed. This means you will not be able to import
+      some modules after installing them with Homebrew, like wxpython. To fix
+      this for the current user, you can run:
+
+        mkdir -p #{user_site_packages}
+        echo 'import site; site.addsitedir("#{homebrew_site_packages}")' >> #{user_site_packages}/homebrew.pth
+    EOS
