You have to options: 1. You can use the equivs package to "fool" dpkg into thinking that a package is there when it is not. This is commonly used, for example, by people who want to install things like apache from upstream source, but then also install Debian packages which depend on apache. 2. You can "forwardport" mysql4 from Sarge to Etch. That is, instead of backporting from Etch to Sarge, as is normally done, you bring the old source package from Sarge to Etch and then build it on Etch. I have written a howto on customizing Debian packages, which also applies to simply recompiling for a different release: http://people.connexer.com/~roberto/howtos/debcustomize I think that option 2 is more correct. That way you know that you are using libraries available in Etch. Regards, -Roberto -- Roberto C. Sanchez http://people.connexer.com/~roberto http://www.connexer.com
