And I probably figured out why. No double colon has anything to do with it. And it's probably the reason why there was acl.html specified instead of acl.html.tmp. the thing is that if you have: filename: another.file in the Makefile and you run make, it will keep that immediate file in place, but if the immediate file is specified using wildcards, e.g.: %name: another.file make will clean that up after using it. I couldn't find why it does that and whether that's documented behaviour, but it certainly is something I didn't expect. You can try that this is fixed by changing: acl.html.tmp: $(srcdir)/aclperms.htmlinc to %acl.html.tmp: $(srcdir)/aclperms.htmlinc
