Presumably, the problem does not occur wih a release, because it already comes with a ./configure script, so the builder does not have to run autoreconf -i, which is when the (broken) ./libtool gets created. So the 'libtool' called is the OpenBSD libtool, which does not have that bug. _______________________________________________ SoX-devel mailing list SoX-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sox-devel
