Take a second look at the definition of the "PREFIX clean" you agreed to before, and the conditions I stated above: all files installed in by APort are in PREFIX, and all references to things installed by APort use PREFIX. That doesn't say anything about how APort references things installed by other ports! Of course, your suggested change fixes some of those cases, but it's not correct for things installed by other ports according to my reading of bsd.port.mk. The port being built things in PREFIX; other ports installed things in LOCALBASE or X11BASE, as appopriate. So fixing references to things in other ports requires s./usr/local.LOCALBASE.g, hence "LOCALBASE clean" for things that fail to deal with that case. As a final note, neither fix corrects the cases where the /usr/local reference that makes things work when LOCALBASE and PREFIX are both /usr/local comes from outside of the ports tree completely. <mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
