OK, _that_ was an interesting question!  I managed to compile aout
perl, but _not_ the default one shipped with FreeBSD.  If you are
interested in this, do the following:

1.  Download ftp://ftp.funet.fi/pub/languages/perl/CPAN/authors/id/GBARR/perl5.005_03-MAINT_TRIAL_5.tar.gz

In fact, any CPAN site will do.

2.  Unpack it.
3.  Download http://www.plab.ku.dk/tobez/FreeBSD-perl-aout/Makefile.SH
    and replace original Makefile.SH in the distribution.
4.  Download http://www.plab.ku.dk/tobez/FreeBSD-perl-aout/hints/freebsd.sh
    and replace original hints/freebsd.sh in the distribution.
5.  Cd to the distribution directory.
6.  $ OBJFORMAT=aout sh Configure -DAOUT -des

This will prepare to make _static_ libperl.a.  You are welcome to try
to build dynamically linked version yourself :-) though I think there
is actually no need to do this to accomplish what you described.

You may also wish to not run -des but rather run Configure in ``slow''
mode and change its defaults for installation paths.

7.  $ OBJFORMAT=aout make
8.  $ OBJFORMAT=aout make test

All tests should be successful.  At least they are on my 4.0-current
machine.

Also:

$ file perl
perl: FreeBSD/i386 compact demand paged dynamically linked executable not stripped
$ file libperl.a 
libperl.a: current ar archive random library

9.  Go root
10. OBJFORMAT=aout make install    (UNTESTED)

Hope this helps.
