Hi all, I attempted to install lyx from the sources (new ver 1.1.5) but it failed to build with the following error messages. It looks like that there is something missing but I do not understand what since I did everything that was required. Could you assist me ? The build was attempted on a Fbsd 3.4 stable box.
