Sorry I know I should have written PR but I'm not sure about correct fix. So
here it goes.
After this changes lang/perl5.8 is still linked to libc_r when compiled with
WITH_THREADS=yes.
It's hardcoded in perl-5.8.2/hints/freebsd.sh
Easily fixed with this patch:

cat > UU/usethreads.cbu <<'EOCBU'
case "$usethreads" in
$define|true|[yY]*)
! lc_r=`/sbin/ldconfig -r|grep ':-lc_r'|awk '{print $NF}'|sed -n '$p'`
case "$osvers" in
0*|1*|2.0*|2.1*) cat <<EOM >&4
I did not know that FreeBSD $osvers supports POSIX threads.

But i) It requires post-changes FreeBSD; and ii) This way libperl.so and the
progs are linked with "-lpthread -lc" Is this correct?
