How physmem2profit client can be installed on linux at current time?

[hvprvtr]

Hello! Rekall framework wrote for Python2. If i build it by Python3 i got specific errors with Python2 syntax.

          exec open("rekall/_version.py").read() in ENV
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
      SyntaxError: Missing parentheses in call to 'exec'. Did you mean exec(...)?
      [end of output]

Same errors for "print [SOME]" and other Python2 items. But. When i install physmem2profit it request Python3.

└─$ python /tmp/physmem2profit/client/physmem2profit/physmem2minidump.py 
/tmp/MyEnv/lib/python2.7/site-packages/rekall/plugins/windows/dumpcerts.py:27: CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team. Support for it is now deprecated in cryptography, and will be removed in the next release.
  from cryptography import x509

How can i solve it? I want just local parse physical memory dump.
