Shortly after initial python-gammu release I've realized that some files were missing in the tarball and this release fixes that.
You are downloading python-gammu source code. To compile it you need some development environment for your platform, Gammu and Python.
Nejjednodušší je instalovat pomocí pip:
pip install python-gammuaa0035ba7ad15219e2488990cd08608a2530dfd1261084c41980fb3e367dd4663724f044e2a9e1dac9b2941c4df98036d8f3e8574112e9845721f21ea42e96f2
