The media_build requires several packages that may not be present on some installation. The build.sh script has a logic to detect the missing parts and to output what's the missing requirements: echo "Checking if the needed tools are present" run ./check_needs.pl (I moved right now the perl-specific checks into check_needs.pl script) Unfortunately, package names are distro-specific. So, as I use only Fedora/RHEL here, the only hints it have are for them. From my experiences, between the rpm-based distros, the package names are either equal or very close, so such hints probably are probably good enough for Suse and Mandriva users. >From what I understand, the standard Ubuntu repositories already provide a package for Proc::ProcessTable. So, the only thing that it is not ok is the package name hint. Could you please provide us a patch adding the Ubuntu (and likely Debian) package name? IMHO, the better would be to modify the check logic, in order to check what's the system, and provide a hint based on it. If the OS type is not found, then fall back to some default. I think that the LSB default to get the distribution is by reading /etc/system-release. Those are provided on RHEL6 and Fedora (plus, the old way: /etc/redhat-release). So, IMHO, all we need to do is to write a logic for the error report part of the check, that opens /etc/system-release, identify what's the distro, and provide the package name and some instructions on how to install the missing parts to the userspace. The right way for adding such logic would be to install the OS's on some VM with the minimum install, run the script and add the missing parts on it.
