That's not your job, the php maintainers have to ensure their packages work, you just have to make sure enough php/mysql/apache stuff is installed to work. If you look at php5-mysql you will see that it depends on phpapi-20060613, which is a virtual package that is provided by php5-cli libapache-mod-php5 php5-cgi libapache2-mod-php5 So a php5 package must be installed. > > At any rate, the problem comes from the orthogonality of the three > "dimensions": > > * PHP 4 vs. 5 > * mysql vs. pgsql > * apache 1 vs. 2 > > The problem exists already in the the current version of the package. > Indeed, the following combination satisfy the dependencies: > > apache2 installed > other apaches NOT installed > libapache-mod-php4 installed > libapache2-mod-php4 NOT installed libapache-mod-php4 depends on apache-common, which in turn depends on apache, so that works ok. You must remember that the dependencies you specify are not all of them, there is a whole tree of dependencies being considered. I think if you consider the tree in all cases you should find that everything that is required is installed, if not then it is probably a bug. Some dependencies are hard to specify in a pleasant way though, so it might get a little ugly.
