**NOTE**: `libssl-dev` is required when compiling Python, installing `libssl-dev` will actually install `zlib1g-dev`, which leads to uninstall and re-install Python versions (installed before installing `libssl-dev`). On Redhat and derivatives the package is named `openssl-devel`. **NOTE**: `libssl-dev` is required when compiling Python, installing `libssl-dev` will actually install `zlib1g-dev`, which leads to uninstall and re-install Python versions (installed before installing `libssl-dev`).

If you want to install a Python interpreter that's available to all users and system scripts (no pyenv), use `/usr/local/` as the install path.

If you encounter this error while installing python and your server is a VPS, the **/tmp** directory where python-build download and compile the packages is probably mounted as **noexec**. You can check with your hosting provider if wether they provide a way to bypass this protection.

If the answer is no, just set the **$TMPDIR** environment variable to wherever you have a write + execution rights. For example: If the answer is no, just set the **$TMPDIR** environment variable to wherever you have a write + execution rights. For example:
export TMPDIR="$HOME/src" export TMPDIR="$HOME/src"

You could try this: On Mac OS X 10.9 and 10.10 you may need to set the CFLAGS environment variable when installing a new version in order for configure to find the zlib headers (XCode command line tools must be installed first):
``` ```
CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install -v 2.7.7 CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install -v 2.7.7
``` ```
It works for me on osx 10.10 DP. ## python-build: definition not found
