Looks like you haven't properly installed the header files and static libraries for python dev. Use your package manager to install them system-wide.

For apt (Ubuntu, Debian...):

sudo apt-get install python-dev   # for python2.x installs
sudo apt-get install python3-dev  # for python3.x installs
For yum (CentOS, RHEL...):

sudo yum install python-devel
For dnf (Fedora...):

sudo dnf install python2-devel  # for python2.x installs
sudo dnf install python3-devel  # for python3.x installs

Update and install redsocks
apt-get update && apt-get install redsocks

Setup transparent proxy (you may need to make file executable with chmod +x enable_socks)
cd <METAMORPH_RELEASE>/redsocks
