pyenv-alias is a pyenv plugin which allows you to specify a 'version name alias' when installing python.
Out of the box, pyenv does not allow you to install multiple copies of the same python version. This can be limiting in situations where you want to have different instances of python with, for example, different compile-time configurations.
git clone https://github.com/s1341/pyenv-alias.git $(pyenv root)/plugins/pyenv-alias
Specify the version alias name using the VERSION_ALIAS environment variable
when performing a pyenv install
For example, building a version of python 2.7.6 with the shared .so:
VERSION_ALIAS="2.7.6_shared" PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 2.7.6
