in thread realloc(): invalid pointer

Thanks for the suggestion. Exporting MALLOC_CHECK_=0 sounds dangerous, so I tried it :).

The realloc() error disappeared, and the process got a lot further, although some of the dependencies failed for other reasons.

Perhaps I should uninstall everything Perl-related and start again.

    Aha! The reason the dependencies failed was 'Out of memory'.

    I'll keep playing and report back.
