21.2.19: Docdir not found

In XEmacs 21.2 (beta19) "Shinjuku" [Lucid] (powerpc-unknown-linux, compiled without problems), configured using `configure --prefix=/usr --package-path=/var/tmp/xemacs-root/usr/lib/xemacs/xemacs-packages --debug=no --error-checking=none --with-pop --mail-locking=flock --with-mule=no --dynamic=yes --lockdir=/var/lock/xemacs', I get the following message after starting xemacs: Couldn't find obvious defaults for: doc-directory exec-directory Perhaps some directories don't exist, or the XEmacs executable, /usr/bin/xemacs is in a strange place? The doc-directory is at /usr/lib/xemacs-21.2-b19/ppc-unknown-linux/, which is the standard place. I compiled 21.2.18 with the same options, and there this problem does not appear. When I run the same executable at the place where it was built, namely /usr/src/redhat/BUILD/xemacs-21.2.19/building/ppc-linux/src/, then it has no difficulties finding its doc-directory, which is called lib-src in this case. I can also make /usr/lib/xemacs-21.2-b19/lib-src a symbolic link to /usr/lib/xemacs-21.2-b19/ppc-unknown-linux/, and the problem disappears. It seems to me that the file names used for make install and those searched for on startup don't agree. -- Martin
