At line 333 of CheckLib.pm, swap:

sub _findcc {
    my @flags = grep { length } map { quotewords('\s+', 0, $_ || ()) }
        @Config{qw(ccflags ldflags)};
[download]

For:

sub _findcc {
    my @flags = @Config{qw(ccflags ldflags)};
    @flags = grep { length } map { quotewords('\s+', 0, $_ || ()) } @f
+lags;
[download]

And the module will load.

And no, I have no idea why that should affect a fix, but it seems to on my 64-bit AS1007 setup.

All I can add at this point is that with the original, when it gets to line 13 of Config_Heavy.pl it goes tits up:

...

But with the change, that line runs fine:

...
>> [0] C:/Perl64/lib/Config_heavy.pl :   13:          die $@ if $@ && 
+$@ !~ /^Can't locate ActivePerl\/Config\.pm/;

>> [0] C:/Perl64/lib/Config_heavy.pl : 1155: my $i = 0;
...

However, even with the fix, the suggested test line produces no output. I'm not sure if that is good or bad?, but I guess it is at least progress:

C:\test>perl -MDevel::CheckLib -e1

C:\test>

Let me know If I can try anything else to help you solve this.
