[Remind-Fans] problem bulding remind

[aalinovi at riseup.net]

I am trying to build the latest remind on OpenBSD-current.
What I get is:

* Installing REMIND (unstripped) *
*                                *
**********************************

mkdir -p /usr/local/bin || true
for prog in remind rem2ps ./../scripts/tkremind ; do  /usr/bin/install -c $prog /usr/local/bin || exit 1;  done
rm -f /usr/local/bin/rem > /dev/null 2>&1 || true
ln -s remind /usr/local/bin/rem

true;  fi
*** Error 2 in rem2html (Makefile:25 'install': @if test "/usr/bin/perl" = "" ; then  echo "Not installing rem2html; Perl is required"; exit...)
*** Error 2 in /home/slaurel/Downloads/remind-04.03.07 (Makefile:23 'install': @make -C rem2html install)
/home/slaurel/Downloads/remind-04.03.07 $

Not knowing programming I have no clue what the problem might be.
Any suggestions would be appreciated.

Thank you
