I think your makefile has the problem.  I am sure that others will
correct me if I am totally mistaken.

I think the problem is that you are building into $(top_srcdir) but
you should be building into $(top_builddir).  When you build in the
same directory as you untar these two directories are the same and
things work.  But when you try to build in a build dir they are
different and therefore missing there.

Try this instead.

INSTALL: $(top_srcdir)/pod/INSTALL.pod
	-rm -f $(top_srcdir)/INSTALL
	-pod2text $(top_srcdir)/pod/INSTALL.pod > $(top_builddir)/INSTALL

README: $(top_srcdir)/pod/README.pod
	-rm -f $(top_srcdir)/README
	-pod2text $(top_srcdir)/pod/README.pod > $(top_builddir)/README

In a nutshell all built targets need to be either relative or use
top_builddir.
