Is it possible to add multiple versions of a module to a minicpan index?

Question

I'm setting up a CPAN::Mini mirror and I want to be able to download multiple versions of modules from the mirror. How do I get it to index more that the latest version of modules I inject:

$ mcpani -v --add --module Foo --authorid DUMMY --modversion 0.001 --file Foo/Foo-0.001.tar.gz
$ mcpani -v --add --module Foo --authorid DUMMY --modversion 0.002 --file Foo/Foo-0.002.tar.gz
$ mcpani -v --update

such that I can do:

$ cpanm -M ~/CPAN [email protected]

NOTE:

The different versions of the module are present within the mirror:

$ find ~/CPAN -name 'Foo-0.00[12].tar.gz'
~/CPAN/authors/id/D/DU/DUMMY/Foo-0.001.tar.gz
~/CPAN/authors/id/D/DU/DUMMY/Foo-0.002.tar.gz

Even if I edit the index file by hand, only the first one listed is available for download:

$ zgrep '^Foo\s' ~/CPAN/modules/02packages.details.txt.gz 
Foo                               0.002  D/DU/DUMMY/Foo-0.002.tar.gz
Foo                               0.001  D/DU/DUMMY/Foo-0.001.tar.gz

I have used CPAN::Mini::Inject in my examples here but I have tried the following with the same outcome:

• cpansite
• App::opan
• OrePAN2
