Only DirOps.pm has a reference to ?BPC_DT_ALL?, there is no
reference to 'BPC_DT_ALL' in the module Lib.pm , could this be why
Perl is failing when it encounters the "use BackupPC::Lib qw(
:BPC_DT_ALL );" statement.
I have also found a change that was introduced in Perl 5.39.1 - see
https://perldoc.perl.org/5.39.1/perldelta#Calling-the-import-method-of-an-unknown-package-produces-an-error
Apparently calling an import method of an unknown package succeeded
silently with Perl 5.38 but at 5.39 produces an error. So perhaps
this has always happened but is now being reported as part of the
upgrade from Perl 5.38 to Perl 5.40.
Good catch!
Doesn't look too controversial to try removing the "qw(...)" from
BackupPC_nightly line 89 and BackupPC_rrdUpdate line 42. :)
For BackupPC the Perl version here is still 5.32 so it may be some
time before I get to test this...
