Can we use a different folder for building?

I raised https://github.com/gugod/App-perlbrew/issues/576 because Perl libraries were failing many tests when I installed, but I closed that issue once I realized that the problem is that my home directory is NFS mounted. That does bad things to permissions. Running perlbrew install worked after I set PERLBREW_ROOT to /tmp/myfolder, because /tmp is a local mount.

That isn't ideal though, because I assume /tmp will be cleared regularly. Even if I used a different folder that isn't cleared regularly, I'd like to use my home directory because NFS mounting has a big virtue: the files will be available regardless of which of our servers I am logged into.

It seems like the solution would be to build Perl in a local directory like /tmp, but copy it back to the final destination in my home directory after it's done. I can probably manage this manually, but is there a way to configure Perlbrew to do this for me?

Start with the perlbrew install entry point and the handling of PERLBREW_ROOT, using the reported /tmp/myfolder setup as the behavioral reference. Determine how a local build directory could be configured while preserving the final installation in the home directory, then verify that installations and their files remain usable after completion.
