Hi Harm,
This is great, thanks. Spent all morning trying to figure out why --disable-werror with configure would not work. Just the wrong flag. Now that I am aware of my stupidity I have been able to build from the code in the git repo with no problem at all. I have been through all this a while ago. One of these days I will learn to take notes and write it all down!
For any others interested, I did:
cd guile
git checkout release_1-8-8
./autogen.sh (this step is not mentioned in the readme's etc)
./configure -disable-error-on-warning
make
sudo make install
