configure does not find installed Perl modules

[Blair Zajac <nospam@thanx>]

When I use WML 2.0.7 configure with the --with-openworld option to
search for already installed Perl modules that WML needs, it does not
properly find them.

This happens to me on Perl 5.6.1.  Configure uses the Perl module's
require_version that comes from Exporter.  This doesn't work on all
of the modules, such as Bit::Vector 6.0 which is installed in my
Perl:

% perl -w -e 'require Bit::Vector; Bit::Vector->require_version(3)'
Can't locate auto/Bit/Vector/require_ver.al in @INC (@INC contains:
/opt/i386-linux/installed/perl-5.6.1/lib/5.6.1/i386-linux
/opt/i386-linux/installed/perl-5.6.1/lib/5.6.1
/opt/i386-linux/installed/perl-5.6.1/lib/site_perl/5.6.1/i386-linux
/opt/i386-linux/installed/perl-5.6.1/lib/site_perl/5.6.1
/opt/i386-linux/installed/perl-5.6.1/lib/site_perl .) at -e line 1

Attached is a patch that uses Perl's normal 'use MODULE_NAME VERSION'
method with a check to see if the version is ANY.

Best,
Blair
