Temporarily I don't have internet connection on my server to redownload perl to make it run under firefox (and, even if, how do I do that under Ubuntu?), but I will try it.

In the meantime, two questions. First has been asked already in my response. Second is, what's the difference between commandline and firefox in terms of perl script? Why does 'commandline' perl break things? Shouldn't it be the same thing?
