So I did this:

mkdir ~/.cpan/CPAN
cp /usr/lib/perl5/5.10/CPAN/Config.pm ~/.cpan/CPAN/MyConfig.pm

Then in MyConfig.pm I did this:

'make_install_arg' => q[UNINST=1],
'mbuild_install_arg' => q[uninst=1],
'makepl_arg' => q[INSTALLDIRS=vendor],
'mbuildpl_arg' => q[--installdirs vendor],

Now everything seems to work OK.

Thanks very much again Reini for your quick fix to the Win7 perlrebase 
bug and for helping me debug this!

I'm going to continue playing with Cygwin Perl and submitting patches to 
CPAN modules for it :)

Also very happy that my perl utils like App::Nopaste now work.
