1. When Quanah announces that RE24 is tagged and ready for release
"-releng" is already removed.

2. It's my strong opinion that if someone unpacks a release tar.gz and
builds it running "make test" should not conflict with an already
installed version of /usr/lib/libl{dap,ber}*.
It's quite normal that you build and test before installing the next
release. Isn't it? Having a separate build system without any
pre-installed libldap is nearly impossible today. On openSUSE even the
software installation tool zypper has a dependency on libldap.

Ciao, Michael.
