I don't know if anyone noticed my previous post on this subject. I
strongly believe rpath should never be used to build xemacs. As I
recall, it was removed because it can cause severe problems. If an
rpath is compiled in to an executable, that is later run in a
different environment, the referenced rpath could contain references
to NFS mounted stuff that is no longer valid, causing severe startup
delays.
If I recall correctly, it was removed at my urging because we
experienced exactly this problem. rpath should never be used to build
xemacs unless it is known by the sysadmin that xemacs will be run in
exactly the same environment in the future.
