Trouble compiling bind916

[bob prohaska]

While trying to compile bind 916 on a Raspberry Pi 3 running
FreeBSD pelorus.zefox.org 13.0-ALPHA2 FreeBSD 13.0-ALPHA2 #1 stable/13-c256213-g03d837b565a: Sat Jan 30 15:07:58 PST 2021     bob at pelorus.zefox.org:/usr/obj/usr/freebsd-src/arm64.aarch64/sys/GENERIC-MMCCAM  arm64

the effort stopped with

[1]    Exit 1                        make -DBATCH > make.log
root at pelorus:/usr/ports/dns/bind916 # tail *.log
===>   fstrm-0.6.0 depends on shared library: libevent.so - found (/usr/local/lib/libevent.so)
===>  Configuring for fstrm-0.6.0
*** Error code 127

Stop.
make[1]: stopped in /usr/ports/devel/fstrm

The punchline seems to be 

root at pelorus:/usr/ports/dns/bind916 # cd /usr/ports/devel/fstrm
root at pelorus:/usr/ports/devel/fstrm # make -DBATCH > make.log &
[1] 1626
root at pelorus:/usr/ports/devel/fstrm # exec: /usr/local/bin/autoreconf-2.69: not found

[1]    Exit 1                        make -DBATCH > make.log

but:

root at pelorus:/usr/ports/devel/fstrm # whereis autoreconf
autoreconf: /usr/local/bin/autoreconf
root at pelorus:/usr/ports/devel/fstrm # 

Is there a fix or workaround? /usr/ports is at Revision: 563453

Thanks for reading,
