cannot build on 9.3-RELEASE

[Roger Marquis]

Cannot build lang/perl* on this recently upgraded (from 8.4) jail due to autoconf errors:

   Shall I use /usr/bin/nm to extract C symbols from the libraries? [y]
    Where is your C library? [/lib/libc.so]
    Extracting names from the following files for later perusal:
            /lib/libc.so
            /usr/lib/libcrypt.so
            /usr/lib/libm.so
            /usr/lib/libutil.so
            /usr/local/lib/libgdbm.so.4
    This may take a while................../usr/bin/nm didn't seem to work right. Trying /usr/bin/ar instead...
    ar: warning: Unrecognized archive format
    /usr/bin/ar didn't seem to work right.
    Maybe this is a Cray...trying bld instead...
    ./Configure: bld: not found
    That didn't work either.  Giving up.
    ===>  Script "Configure" failed unexpectedly.
    Please report the problem to perl at FreeBSD.org [maintainer] and attach the
    "/usr/ports/lang/perl5.18/work/perl-5.18.2/config.log" including the output
    of the failure of your make command. Also, it might be a good idea to provide
    an overview of all packages installed on your system (e.g. a /usr/sbin/pkg_info -Ea).
    *** [do-configure] Error code 1

Anyone seen this?  Any recommendations?
