I had to find out that the build process isn't so easy to solve. However I found another approach for you to get the old version of gedit and gedit-r-plugin up and running.
First removing the traces of your gedit compiling and installing tries (change the paths respectively to fit your situation).
cd ~/your build dir of gedit-plugins/
sudo make uninstall
cd ~/your build dir of gedit/
sudo make uninstall
The next command uninstalls the eventually existing 3.18.3 version of gedit, gedit-dev, gedit-plugins and gedit-common.
sudo apt-get remove gedit gedit-dev gedit-plugins gedit-common
Best to do the following steps in a clean seperate directory.
Now downloading the proper dependencies package for gedit-common 3.10.4 and installing it.
wget http://mirrors.kernel.org/ubuntu/pool/main/g/gedit/gedit-common_3.10.4-0ubuntu13_all.deb
sudo dpkg -i gedit-common_3.10.4-0ubuntu13_all.deb
Then downloading the proper gedit 3.10.4 package and installing it
wget http://mirrors.kernel.org/ubuntu/pool/main/g/gedit/gedit_3.10.4-0ubuntu13_amd64.deb
sudo dpkg -i gedit_3.10.4-0ubuntu13_amd64.deb
And downloading the proper gedit-dev 3.10.4 package and installing it.
wget http://mirrors.kernel.org/ubuntu/pool/main/g/gedit/gedit-dev_3.10.4-0ubuntu13_amd64.deb
sudo dpkg -i gedit-dev_3.10.4-0ubuntu13_amd64.deb
Finaly downloading the proper gedit-plugins 3.10.1 package
wget http://mirrors.kernel.org/ubuntu/pool/universe/g/gedit-plugins/gedit-plugins_3.10.1-1ubuntu3_amd64.deb
We need to unpack this downloaded .deb file because we need to do two changes (sudo keps the packages owner intact).
sudo dpkg-deb -R gedit-plugins_3.10.1-1ubuntu3_amd64.deb tmp
First we are editing tmp/DEBIAN/control and change python3 (<< 3.5), python3 (>= 3.4~), python3.4 to python3 (>= 3.5~), python3.5.
sudo nano tmp/DEBIAN/control
Then we edit tmp/DEBIAN/postinstand change py3compile -p gedit-plugins /usr/lib/x86_64-linux-gnu/gedit/plugins -V 3.4 to py3compile -p gedit-plugins /usr/lib/x86_64-linux-gnu/gedit/plugins -V 3.5.
sudo nano tmp/DEBIAN/postinst
Now we can pack a new .deb file.
sudo dpkg-deb -b tmp gedit-plugins_3.10.1-1ubuntu4_amd64.deb
And changing ownership of the new .deb file (replace username with your username)
sudo chown username:username gedit-plugins_3.10.1-1ubuntu4_amd64.deb
Now finally installing it.
sudo dpkg -i gedit-plugins_3.10.1-1ubuntu4_amd64.deb
And now we download the proper gedit-r-plugin 0.8.0.2 package and install it.
wget http://mirrors.kernel.org/ubuntu/pool/universe/g/gedit-r-plugin/gedit-r-plugin_0.8.0.2-Gtk3-Python3-1ubuntu1_all.deb
sudo dpkg -i gedit-r-plugin_0.8.0.2-Gtk3-Python3-1ubuntu1_all.deb
Only thing now left is protecting this all from upgrading.
sudo apt-mark hold gedit-common gedit gedit-dev gedit-plugins gedit-r-plugin
