Well, that's a pain.  It might be worth talking to the xpdf author
about when the program returns error codes.

The other option when a program doesn't return an error code but
prints to stderr is to capture stderr and watch for a given message
(or any at all).

You do that with IPC::Open3.  perldoc perlfaq8 has a section that
describes how to capture both stderr and stdout.  That would replace
the fork/exec that is done currently in run_program().
