Yes it does work in offline mode. The same minimal file just fails when
running under Apache/mod_perl. I have also tried running the script
offline as user 'nobody', which is the same as how Apache runs. Is
anyone aware of any other permissions differences, apart from the user
we are running as?

Ok, I don't know much about this, but it sounds reasonable. Since we are
apparently running another program (ispell), I guess there is some kind
of mechanism for piping stuff between the processes, and I could imagine
that using stdin somehow.
If this is the case, then is anyone aware of a workaround for doing this
under Apache/mod_perl? (apart from running as a CGI, which is not really
an option for performance reasons).
