C:\Documents and Settings\UserName\.cpanplus\
tree), and that cache contains configuration parameters, including the current (=default) Perl installation top directory.
Also, after extensive googling, quite far away in a search result list, I have found this:
You only need one installation of CPANPLUS for all versions of Perl. As of version 0.04, CPANPLUS keeps different directories under its home directory for each version of Perl:
.cpanplus/ authors/ id/ # tarballs live here 5.6.0/ build/ 5.7.3/ build/
This prevents conflicts.
- Installing several Perl versions is ok and supported
- CAPNPLUS supports working in a multi-perl installation environment, but you must clear the "CPANPLUS cache" when shifting from one installation to the other (or use some other alternatives listed in that URL)
- CPANPLUS documentation is meager and practically non-existent. I found the URL quoted above by accident, and its parent URL is broken.
That has been an excruciating experience. I have spent days wrestling with this.
