PDF::parse: cannot find pdf parser /usr/local/bin/acroread

[Walter Hofmann <walterh@gmx.de>]

I get the following error message in a mail from Anacron:

/etc/cron.daily/htdig:
PDF::parse: cannot find pdf parser /usr/local/bin/acroread

Looks like some perl script is misconfigured. But I cannot find a way to
set the path for acroread. Where is it set?
