No additional dependencies except Python 2.7/3.x interpreter are required.
Preferable way is to download tarball with the signature:
$ [fetch|wget] http://www.pygost.cypherpunks.ru/pygost-5.13.tar.zst
$ [fetch|wget] http://www.pygost.cypherpunks.ru/pygost-5.13.tar.zst.{asc,sig}
[verify signature]
$ zstd -d < pygost-5.13.tar.zst | tar xf -
$ cd pygost-5.13
$ python setup.py install

Also there is example P2P F2F E2EE IM written on Python, that uses PyGOST with PyDERASN: GOSTIM (sig) (17 KiB). It is described on russian in that article. You have to verify downloaded tarballs authenticity to be sure that you retrieved trusted and untampered software. There are two options:
Use GNU Privacy Guard free software implementation. For the very first time it is necessary to get signing public key and import it. It is provided here, but you should check alternate resources.
