script runs from command line and as CGI, not under ePerl/mod_perl

[Todd Finney <suppressed>]

I'm using Business::Shipping to pull rate information from the USPS site 
for our online stores.  This is nothing new, I've been doing this for a 
long time on another server without a hitch.

I have a test script that Dan Browning (author of Business::Shipping) gave 
me.  It runs just fine as a command line script and as a cgi script, and 
gives the expected result.

Result: [http://heavy.boygenius.com/temp/test.cgi]

However, when I take the same script and run it in my Apache/ePerl 
environment, it fails with no errors, no output, no nothing.

(I needed to shut off warnings to eliminate subroutine redefined warnings)

Result: [http://heavy.boygenius.com/temp/test.phtml]

That should sit for a while, then reward you with a plain white screen.  I 
get nothing in the server error logs, and nothing in the B::S logs.

When I su to the web user and run the phtml file through the eperl parser 
via the command line ("eperl -B '<?' -E '!>' test.phtml"), it works just fine.

All of the other phtml files on the server - and there are a lot of them - 
work as expected.

This is running on a fresh debian sarge box using a locally compiled Apache 
1.3.37 and mod_perl.  The ePerl instance was installed via CPAN.  I use 
this same setup on all of my servers, and I've never had a problem like 
this before.

If anyone could offer some advice on what might be happening here, I'd 
really appreciate it.

thanks,
Todd
