 We don't support building a static OpenRC with PAM.
 You may need to use PROGLDFLAGS=-Wl,-Bstatic on glibc instead of just -static.
+If you debug memory under valgrind, add -DDEBUG_MEMORY to your CPPFLAGS
+so that all malloc memory should be freed at exit.
 
 You can also brand OpenRC if you so wish like so
 BRANDING=\"Gentoo/$(uname -s)\"
