Usually when MacPerl crashes when you're using modules, it's because 
you haven't given enough memory to MacPerl.  You need far more than 
the default if you use almost any module.  Certainly that's the case 
with something the size of LWP.  My memory allocation for MacPerl is 
set to 40 Mb.

But there does seem to be a problem:  If I take your script and 
modify it slightly to point to a file that exists on my disk, it 
converts the file URL to a relative path:

404 (Not Found) File `:Portable Bunny:Game Sprockets Readme' does not exist
Client-Date: Thu, 20 Apr 2000 12:11:32 GMT

To fix that, just removing one of the slashes seems to do it 
(file://Portable...):

200 (OK)

Content-Length: 3394

I'll look into this and see if a patch needs to be sent to Gisle Aas. 
IIRC, there was a change to the file URL syntax where the thing after 
the // is a volume name, in which case it seems to me that // rather 
than /// is the preferred syntax, anyway.

But otherwise, I'm not seeing any crashing, and MacPerl's memory 
usage is not a problem.  I'm running 9.0.4 on an iBook.
