+
+For php-timezonedb it specifically mentioned that it was built against
+the TS version where as the core PHP was NTS (TS vs NTS in the build ids
+it was comparing).
+
+
+For the other two, they complained about missing symbols when the TS
+version appeared. I forget the symbol itself but it was mentioned
+global_config.
+
+They had the same error today (presumably after reverting) so had to
+rebuild again.
+
+I guess enabling TS vs. NTS changes things more subtly than it might appear.
+
+Easy enough to reproduce - just install them and run "php -v" on the
+command line to see the list of errors.
