Adding optional inputs to kdelibs, I notice that acl is not recognised. The reason is that the header files are not installed. Would that be easy to modify? Maybe by changing the line (zero? (system* "make" "install" "install-lib"))) to (zero? (system* "make" "install"))) or not replacing the normal install phase (but then there may be a reason for this special command!).
Concerning the acl test failures, I tried #:tests? #t and found that there is no "check" target. A good reason for the tests to fail... Andreas
