The basic problem is that rtld-elf is more than happy to load two different libraries wit virtually the same name at once, leading to massive errors. FreeBSD's rtld-elf is the *only* runtime loader that I have ever encountered which allows this broken behavior. Apparantly, Polstra believes that there exist a situation where loading two instances of a library or two versions of a library is *not* an error. If rtld-elf did not do this, it would catch or prevent most of these errors in the first place. /Joe To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
