Can you replicate?
No (Windows Vista 32-bit):

This is perl 5, version 14, subversion 2 (v5.14.2) built for MSWin32-x
18:58 >pmvers XML::LibXML Digest::SHA1
18:59 >pmvers Digest::SHA1 XML::LibXML
Well, here’s the comment in the code immediately before line 190 of DynaLoader.pm:
# Many dynamic extension loading problems will appear to come from
# this section of code: XYZ failed at line 123 of DynaLoader.pm.
# Often these errors are actually occurring in the initialisation
# C code of the extension XS file. Perl reports the error as being
# in this perl code simply because this was the last perl code
# it executed.
So — maybe the XML::LibXML build was faulty? Have you examined the build log? Tried reinstalling?
