Perl 5.8.0 h2xs test 95 fails when locincpth is undefined

Summary:  When configuration parameter locincpth (local include path)
is undefined, h2xs test 95 fails.

Explanation:  While installing perl 5.8.0 on a Sun Netra running
Solaris 2.8, all "make test" tests passed except h2xs test 95.  That
test died while trying to split the uninitialized value,
$Config{locincpth}.  Arusha, my system management tool of choice,
deliberately undefined Locincpth by running perl's configure script
with the "-Aundef:locincpth=" parameter.

Question:  Must locincpth have some value or can h2xs be patched to
accept undefined locincpth values?

--------- More background material below ------------

Here is a detailed excerpt from the h2xs test:

% cd lib
% ../perl h2xs.t
1..113
ok 1 - open 'h2xst.h'
ok 2 - close 'h2xst.h'
...
ok 94 - running ../perl "-I../lib" "-I../../lib" ../utils/h2xs -f -n h2xst
h2xst.h -b 5.8.0 2>&1 
not ok 95 - running ../perl "-I../lib" "-I../../lib" ../utils/h2xs -f -n
h2xst h2xst.h -b 5.8.0 2>&1
#     Failed test (h2xs.t at line 169)
#          got: 'Use of uninitialized value in split at ../utils/h2xs line

...
ok 113 - unlink 'h2xst.h'
# Looks like you failed 1 tests of 113.


Looking near line 711 of h2xs, I find:

	@paths = (File::Spec->curdir(), $Config{usrinc},
                (split ' ', $Config{locincpth}), '/usr/include');


Suspecting that locincpth might not be defined, I tried:

% ./perl -Ilib -MConfig -wle 'print $Config{locincpth}'
Use of uninitialized value in print at -e line 1.

I'm using Arusha <http://arusha.sourceforge.net>, a system management
tool to configure and install perl (and other applications).  It
explicilty undefines locincpth during perl's configuration.  Among many
configuration arguments, Arusha specifies "-Aundef:locincpth=".
