You're welcome.

The changes to libtool.m4 are not important.  They came, as you said, as 
a consequence of running autoreconf -i -f to include the changes in 
configure.ac

Another thing, perhaps you should stipulate that one needs to set 
PYTHONPATH to include <prefix>/lib/python<version>/site-packages if one 
does not install in either /usr/local or ~/.local

Also, perhaps you should consider to build the docs  (Doxygen) as part 
of the regular build.  In any case, you should change the line

   @$(DOXYGEN) $(top_srcdir)/Doxyfile || true

to

   @$(DOXYGEN) $(top_builddir)/Doxyfile || true

if one does out-of-source-directory builds (as I prefer to do - do not 
sh*t where you eat kinda policy :-)

And finally, you should probably automatically detect if HepMC is of the 
right version (i.e., 2.x), since HepMC 3 has changed a lot in the API.

Yours,
