In 5.8.0a2, LWP::Simple's head function always fails.
Code previously run under 5.2.0r4 failed without exception until
head() was replaced with get() (less efficient but a workaround).
Relevant lines:
use LWP::Simple qw(get head);
if (head($url)) { ...
head() always fails. get() works.

Thanks for the report. webgod@mindspring.com reported that
the Net/HTTP/ directory is missing (I removed it
accidentally, probably thinking it was part of libnet
instead of LWP); adding it back in from the 5.6.1r1 lib
directory, or from the LWP distribution, fixes the problem.
It will be fixed in a future release.s
