h3. Tweaks * If the packages manager complains about @lib32readline5-dev@ being missing, replace it with @lib32readline-gplv2-dev@ in the command line. * If the @/usr/lib/zconf.h@ header is missing, you will have to create a symlink there:
ln -s /usr/include/x86_64-linux-gnu/zconf.h /usr/lib/zconf.h
* If you see errors about incompatible library versions, you may need some symlinks. For example:
sudo ln -s /usr/lib32/libstdc++.so.6.0.14 /usr/lib32/libstdc++.so
sudo ln -s /usr/lib32/libz.so.1.2.3.4 /usr/lib32/libz.so
