I went too fast on that changes, GTK build is broken, so I propose to merge both environnements if Python3 is 
installed in prefix:

+elif os.path.isfile (os.path.join(prefix, 'bin', 'python3')):
+    python_version = subprocess.Popen([os.path.join(prefix, 'bin', 'python3'), "--version"], 
stdout=subprocess.PIPE).stdout.read()
+    _python_ver = re.search(r"Python ([0-9]+[.][0-9]+)[.]", python_version.decode('utf-8')).group(1)
+    _python_install_path = os.path.join(prefix, 'lib', 'python' + _python_ver,
+                                        'site-packages')
+    append_autogenargs('libxml2',
+                       '--with-python-install-dir=' + _python_install_path)
+    environ_append('PYTHONPATH', _python_install_path, ':')
+    _python_library_path = os.path.join(prefix, 'lib')
+    environ_append('LDFLAGS', '-L' + _python_library_path)
+    _python_ver = str(sys.version_info.major) + '.' + str(sys.version_info.minor)
+    _python_install_path = os.path.join(prefix, 'lib', 'python' + _python_ver,
+                                        'site-packages')
+    environ_append('PYTHONPATH', _python_install_path, ':')
+    _python_library_path = os.path.join(os.environ['PYENV_ROOT'], 'versions',
+                                       os.environ['PYENV_VERSION'], 'lib')
+    environ_append('LDFLAGS', '-L' + _python_library_path)
+    os.environ['PYTHON'] = sys.executable
+    del python_version

Is it not too much confusing?

Thanks, Pascal.
