Just stumbled over this one, too. I don't think it's very nice to suddenly let ./configure --enable-debug die when valgrind headders are not present, and I didn't request valgrind support in ext/pcre. Suddenly all of my travis builds failed, for no apparent reason, despite --disable-all I think it should only fail hard, if explicitly requested. -- Regards, Mike
