I recognise my writing style :)

Is cgi/get_journals returning any data?

Try knocking up a quick script which basically does "perl get_journals" 
- but includes all the stuff you need to get the library path for 
EPrints, and provides the current repository.

The get_journals script as on the page should be dumping html fragments 
into your apache error_log (the ' warn "\n\n$html\n\n";' line in 
'process_journal' - if you're seeing nothing, then the LWP::UserAgent 
call isn't getting any data - add some debugging statements into the 
code to check the value of $query, and of $content (in 'get_journals')
