i've got two debian boxes recently fsckd and partitioned and installed via potato ISO cd roms.
on one, i downloaded the vpnd tarball and did # ./configure # make and voila, no troubles. [vpnd from http://www.crosswinds.net/~anstein/unix/vpnd.html ] on the other debian box, i get # ./configure Please install the package zlib 1.1.3 or later. You can find it at: http://www.cdrom.com/pub/infozip/zlib/ If your system has libz.so installed please make sure that the zlib-devel rpm is installed, too. Building vpnd with runtime compression disabled. # apt-get install zlib1g-dev Reading Package Lists... Done Building Dependency Tree... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation: Sorry, but the following packages have unmet dependencies: zlib1g-dev: Depends: zlib1g (= 1:1.1.3-5) but 1:1.1.3-9 is to be installed my /etc/apt/sources.list are set to potato: #deb file:/cdrom stable main deb http://http.us.debian.org/debian potato main contrib non-free deb http://non-us.debian.org/debian-non-US/ potato/non-US main contrib non-free 1) why would zlib1g-dev and zlib1g versions not match? 2) what method could i have implemented to get one debian box to compile vpnd, but not the other? tres bizarre.
