Problem building perl5 on NetBSD 6 / Sparc64

Hi,

I try to install a MySQL server on a Sun Blade 2000 computer running 
NetBSD-6. I tried to use an older pkgsrc-branch (pkgsrc-2012Q3) and 
NetBSD-current too but got the same error.

I got the following output:


----------------
Updating makefile...
Now you must run 'make'.

If you compile perl5 on a different machine or from a different object
directory, copy the Policy.sh file from this object directory to the
new one before you run Configure -- this will help you with most of
the policy defaults.
