can not install using CPANPLUS 0.9160, perl 5.10.1 about test-file HOT 4 CLOSED

Noted, but my first suspicion is that this is a problem with CPANPLUS. Can you run the Makefile.PL manually?

Hmm, yes, manual installation steps run smoothly and easily.

I was able to reproduce this on perl5.10.1 and CPANPLUS 0.9160. I've also been able to make it work by getting rid of:

-e use strict; BEGIN { my $old = select STDERR; $|++; select $old; $|++; $0 = shift(@ARGV); my $rv = do($0); die $@ if $@; }

The problem here is the do(). The Makefile.PL here is a modulino (https://www.masteringperl.org/2015/01/makefile-pl-as-a-modulino/). If you load it as a module, it doesn't execute. You're supposed to run Makefile.PL as a script.

Starting in CPANPLUS 0.76, there was a perlwrapper feature and it was apparently configurable. In CPANPLUS-0.9158, released this May after seven years of no updates, changed this to a constant. The cpanp_run_perl script what used to be the value of perlwrapper is basically the same thing as that command line.

CPANPLUS does this as a kludge to set auto flushing on the filehandles. I think there's probably a better way to do what it wants to do while avoiding the do. Perhaps exec.

I get too much benefit from my modulino approach, and neither cpan nor cpanm have this issue.

Fair enough. Thank you so much for the explanation!
