Sorry, I misread your report until now - you're talking
about a .par file, not a packed executable.
I think what happens is a kind of chicken and egg problem:
- your .par contains different versions of File::Temp etc
than installed on the target machine
- conceptually we would like "perl -MPAR foo.par"
to behave like
- extract file.par into temporary directory /tmp/foo123
- run "perl -I/tmp/foo123 /tmp/foo123/foo.pl"
(i.e. "/tmp/foo123" is at the start of @INC)
- in order to get to the modules in the .par file, PAR.pm
needs some modules, e.g. File::Temp
- hence it already has loaded the target system's File::Temp
before it even gets to consider the (different) copy included
in the .par
All modules cited in your report are in this category
"required by PAR.pm to extract stuff from a .par file".
(Digest::SHA1 is a special case that's even weirder.)
Sorry, I see no sane way to make this work.
