It is a custom perl generated from the real perl tarball, not a vendor
modified one. The only "customisation" is to change the name of the perl
binary itself (together with all the library paths etc). This is so that
there is no chance of ever getting vendor and this custom perl packages
Thank you all for your suggestions. I will see whether I can "persuade"
them to upgrade.
