Indeed - a useful tool is 'corelist', which will print the first
version of Perl which shipped a given CPAN module in the core:

    $ corelist File::Spec

    File::Spec was first released with perl 5.00405

(i.e. Perl 5.4)

Which leads to the question: what is the minimum version of Perl we
can rely on in LibreOffice?  Currently configure.in checks for Perl 5,
but the Perl currently in solenv almost certainly requires Perl 5.8
(first released 2002).

Even Perl 5.10 (first released 2007) is no longer maintained upstream,
although it is still the one shipped in Debian squeeze/lenny (current
stable/oldstable):

 http://www.cpan.org/src/
 http://packages.debian.org/squeeze/perl

Would it be reasonable to bump the configure.in check to look for Perl
5.10, for now?  I might try to replace the macro with one from the
autoconf archive:

http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_prog_perl_version.m4

Kind regards,
