Requirements: 1. You must have the Mark5 streamstor libraries installed 2. difxmessage is needed To install from a fresh svn checkout, run the following: aclocal autoconf autoheader automake -a ./configure --prefix=${DIFXROOT} make # (su root?) make install After an svn update, these steps do not need to be rerun. at most, running autoreconf should be enough, but usually just "make" will update everything properly.
