Hi,
Devel-CheckLib is more-or-less unloadable when using the MinGW compiler with ActivePerl. Nevertheless, I built and installed it on the x86 version of ActiveState build 1005 (perl-5.10). I skipped the 'dmake test', because the tests all fail anyway - ie I ran 'perl Makefile.PL' followed by 'dmake install'.

If I then run 'perl -MDevel::CheckLib -e 1' I get: 
C:\_32\comp\Math-GMP-2.06>perl -MDevel::CheckLib -e 1
%Config::Config is read-only
BEGIN failed--compilation aborted at C:/_32/ap1005/lib/ActiveState/Pat
+h.pm line
12.
Compilation failed in require at C:/_32/ap1005/lib/ActivePerl/Config.p
+m line 46.

Compilation failed in require.
BEGIN failed--compilation aborted.

But if, in the same directory, I run 'perl -Mblib -MDevel::CheckLib -e 1', then there's no problem: 
C:\_32\comp\Math-GMP-2.06>perl -Mblib -MDevel::CheckLib -e 1
Set up gcc environment - 3.4.5 (mingw-vista special r3)

I can even do: 
C:\_32\comp\Math-GMP-2.06>perl -Mblib -MDevel::CheckLib -e "print $Dev
+el::CheckLib::VERSION"
Set up gcc environment - 3.4.5 (mingw-vista special r3)
0.91

But ... the thing is .... the blib does *not* contain a CheckLib.pm - it's a Math-GMP-2.06 blib !!

How is this possible ? Why should the invocation of a blib that contains nothing useful make such a difference ? What steps can I take to try and make sense of this ?

Btw, it's exactly the same scenario with ActivePerl build 1200 (perl-5.12).
And it doesn't have to be a Math-GMP blib. *Any* valid blib structure will do.

Cheers,
Rob
