In fact the installed release is 5.8.8! What happened when I tried to install (using cpan) File::Find is that cpan itself tries to compile Perl 5.13.9. "It's most likely a dependency of the current version of File::Find" said the datacenter support. And "This isn't something we can troubleshoot."
So what to do? File::Find cannot be installed? Or an older release but is that possible thru cpan?
