I have a clean and updated raspbian stretch on rpi 3B+.
I created a virtual environment. Activated it. Compiled python 3.7 in the venv. Installed pyephem into it with pip.
All is working fine in the venv with python 3.7. Now I want to install pygame into this venv to add pygame functionality to my python 3.7 pyephem scripts.
I read elsewhere to first do this:
sudo apt-get build-dep python-pygame
sudo apt-get install python-dev
I am concerned that this will corrupt my clean python 3.7 compiled install. I could find no assurance that this would be a compatible solution for any and every current python version as well as versions that might be released tomorrow. So, trying to jump right in with a pip install of pygame, without first using those two lines above ...
pygame install failed with sdl-config missing
Then I installed and used apt-file search "sdl-config" to find its dependencies and install them ...
(venv) $ sudo apt install libsdl1.2-dev
that resolved the first problem of the missing sdl-config, but now...
"pkg-config freetype2" failed
(venv) $ apt-file search "freetype2"
decided libfreetype6-dev was most thorough dependency.
(venv) $ sudo apt install libfreetype6-dev
it is already the newest version.
How do I get past this and proceed to get pygame installed into my venv that has python 3.7.0 and pyephem working perfectly already? And those two commands mentioned earlier, are they for both python3.x and python2.7, and how would one find out the known compatability and incompatibility with particular python and system versions?
if it helps, here is the complete output from the install pygame attempt...
(venv) $ python3 -m pip install pygame

You are using pip version 18.0, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I intentionally left out the details of my terminal prompt.
Thank you for any insight into resolving this present difficulty.
