Why, given the following arguemnts to configure:

./configure \
--with-config=DailyDump \
--prefix=/opt/amanda \
--with-index-server=amanda.meadwestvaco.com \
--with-tape-server=amanda.meadwestvaco.com \
--with-tape-device=chg-multi \
--with-changer-device=chg-multi \
--with-user=amanda \
--with-group=operator \
--with-debugging \
--sbindir=/opt/amanda/sbin \
--libexecdir=/opt/amanda/libexec \
--libdir=/opt/amanda/lib \
--with-configdir=/opt/amanda/etc \
--with-gnutar-listdir=/opt/amanda/var/gnutar-lists \
--mandir=/opt/amanda/man  \
--with-buffered-dump \
--without-rundump  \
--with-maxtapeblocksize=256

Do the files, which I think should  be installed in /opt/amanda/lib,
actually get installed in /opt/amanda/lib/amanda ?

amanda@amanda:/opt/amanda$ cd libexec
amanda@amanda:/opt/amanda/libexec$ ls
amanda
amanda@amanda:/opt/amanda/libexec$ cd amanda
amanda@amanda:/opt/amanda/libexec/amanda$ ls

One of the main causes of the fall of the roman empire was that, lacking
zero, they had no way to indicate successful termination of their C
programs.
