Have anyone tried to build perl on NetBSD-1.3_ALPHA ?

On NetBSD/i386 1.2.1, it builds successfully, including make test, as
demonstrated below:
All tests successful.
u=3.93  s=5.21  cu=164.77  cs=95.55  scripts=151  tests=4819
$ cd t
$  ./perl lib/complex.t | grep -v ok
1..1001
$ uname -a
NetBSD netbsd.ipv6.uni-c.dk 1.2.1 NetBSD 1.2.1 (NBA) #4: Wed Oct  8

nba@netbsd.ipv6.uni-c.dk:/usr/src/sys/arch/i386/compile/NBA i386
$ pwd
/raid/erik2/perl5.004_04/t


On NetBSD/{i386,mac68k}-1.3_ALPHA, one of the tests fails (same data
on both platforms, and same for both of perl5.004_0[34]):

 ./perl lib/complex.t | grep -v ok

I'm asking on NetBSD-current, as the version of NetBSD is significant,
but I really don't have a clue where the problem is.

I'm also building perl on a DECStation running NetBSD/pmax-1.3_ALPHA,
but won't have any results until tomorrow.
