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 
mixed up.

Thank you all for your suggestions. I will see whether I can "persuade" 
them to upgrade.
