In GraphicsMagick I use find+cpio to copy directories.  This allows 
using egrep to filter out files which should not be distributed.

Is this combination more portable than GNU tar?

DISTDIRS = locale scripts www PerlMagick TclMagick
dist-hook:
        ( \
          builddir=`pwd` ; \
          cd $(srcdir) && \
          ( \
            for dir in $(DISTDIRS) ; do \
              find $$dir -depth -print | egrep -v 
'(~$$)|(/\.hg)|(/\.#)|(/\.deps)|(\.pyc)' \
                | cpio -pdum $$builddir/$(distdir) 2> /dev/null ; \
            done \
          ) \
        )
