This looks like the last issue with Git 2.12.2. This time the machine is Fedora 25. I configured with PERL_PATH=/usr/local/bin/perl. The local Perl was built specifically for this error, and it includes ExtUtils/MakeMaker.pm: $ find /usr/local -name MakeMaker.pm /usr/local/lib/perl5/5.24.1/ExtUtils/MakeMaker.pm $ make all ...

Failed to build Git /usr/local/bin/perl is on path but Git is using the old one in /usr/bin: $ which perl /usr/local/bin/perl It appears Git is not honoring the request for the updated Perl. Thanks,
