rebuilding a module with CPAN

Hello all,

So, my bad day started with an over-zealous rm -rf. It has to do with
fink and darwin, and it's ugly, but suffice it to say, I no longer have
much of a /usr/local directory. I've been reinstalling since. I ran
into some troubles with ImageMagick. I use
Image::Magick::Thumbnail::Fixed on a test server on my mac, and when I
tried opening the script that called it, it couldn't find
/usr/local/lib/libmagick.*.dylib, namely because I rm'ed it.

I can't get CPAN to rebuild the module, because according to its
database, its up-to-date and everything's ok. I tried using the
ExtUtils library to uninstall the module, essentially:

$inst = ExtUtils::Installed->new();
unlink $inst->files('Image::Magick::Thumbnail::Fixed');
unlink $inst->packlist('Image::Magick::Thumbnail::Fixed');

which seemed to work. I went into the CPAN shell to reinstall, and
CPAN still thinks it is installed. Is there a way to force CPAN to
rebuild the module? I've tried the following to no avail:

cpan> force get Image::Magick::Thumbnail::Fixed
cpan> force make ...
cpan> force install ...

test doesn't even actually perform any tests! It just keeps telling me
that everything is current and ok.

I'm running perl5.8.8 on MacOSX Darwin (10.4.7)

Thanks a bunch,
Matt
