No problem.
The fix came right in time!
I was really desperate and looking for other packagers for perl.

Great news, thank you so much!

No, I ran it on a different clean machine.
I guess, it worked fine on the build machine because it loaded everything from
system-wide perl.
The simplest way to get a clean environment for me is to setup a minimalistic
chroot:
mkdir -p chroot/{dev,tmp,lib64}
mount --rbind /dev chroot/dev
mount --bind /lib64 chroot/lib64
mount --bind -o ro,remount /lib64 chroot/lib64 # yes, a separate remount is
needed with util-linux < 2.27
cp hello.exe chroot/
chroot ./chroot /hello.exe
It has a downside of running hello.exe as root though.
Not sure, how to plug this in Packer's self-tests though.
An LD_PRELOAD library that hides system-wide perl might work.
