What OS do you use on your Pis? You may want to use checkinstall to build a package easily and distribute the package to other machines.
Sorry if my advice was wrong.

    Debian Wheezy, also referred to, I think, as Raspbian. All cards have had the OS created by the same process. I hadn't heard of checkinstall. Thanks - I'll investigate.

    Update: I don't think checkinstall is going to help me, although I'll bear it in mind. The problem is that there's something - a file, some hidden variable or something else - that I'm not copying and that therefore I don't know how to put into checkinstall. If I knew what to copy, I can imagine situations where it might help. At the moment, I just want to know what it is I'm failing to copy.

      Well, checkinstall -D 'make install' should have made full package of perl, with everything that make install was going to install. It can be checked using dpkg-deb -c file.deb. Maybe the problem is not caused by perl itself, but by some package that was installed on the building machine as perl dependency, but not on the others.
