What's the output from just:
perl -MNet::SMTP -we1
I have not looked deeply at this, but the error you're getting means
"we tried to load it before and failed, and here you are trying
again".
This is almost definitely due to this line in git-send-email:
if (eval { require Net::SMTP; 1 }) {
And more generally, this code is all buggy:
4 matches for "eval.*require" in buffer: git-send-email.perl
153:my $have_email_valid = eval { require Email::Valid; 1 };
154:my $have_mail_address = eval { require Mail::Address; 1 };
1118: if (eval { require Net::Domain; 1 }) {
1129: if (eval { require Net::SMTP; 1 }) {
Well, "buggy" in the sense that we're just happy-go-lucky trying to
load these modules, and if they have an error we don't report it, then
when we try to load them again perl just emits a generic error saying
you're trying to require() something that already failed somewhere
before, a minimal test case for that is:
$ cat /tmp/Fails.pm
package Fails;
die "oh noes";
$ perl -I/tmp -we 'eval { require Fails }; require Fails'
Attempt to reload Fails.pm aborted.
Compilation failed in require at -e line 1.
Whereas what we really want to do is some variant of:
$ perl -MData::Dumper -I/tmp -we 'eval { require Fails } or warn
$@; require Fails'
oh noes at /tmp/Fails.pm line 2.
Compilation failed in require at -e line 1.
Attempt to reload Fails.pm aborted.
Compilation failed in require at -e line 1.
Or even the more adventerous, this can have some bad side-effects with
some libraries (you lie to perl saying you haven't seen it before),
but I doubt Net::SMTP cares much, particularly when we're just about
to report an error:
$ perl -MData::Dumper -I/tmp -we 'eval { require Fails } or do {
delete $INC{"Fails.pm"} }; require Fails'
oh noes at /tmp/Fails.pm line 2.
Compilation failed in require at -e line 1.
