pkgtools/digest wants pkgsrc gcc after bootstrap, circular dependency

[Hauke Fath <hf%spg.tu-darmstadt.de@localhost>]

All,

after bootstrapping pkgsrc on an OpenIllumos system with gcc 4.3, any 
attempt at building a package fails with a circular dependency in 
digest.

The bootstrap was configured as

#!/bin/sh

PATH=/usr/sbin:/usr/bin:/usr/gcc/4.3/bin
export PATH

cd /misc/pkgsrc/bootstrap || exit 1

sh bootstrap \
        --workdir /root/pkgsrc_bootstrap/work \
        --prefix /usr/pkg \
        --pkgdbdir /usr/pkg/pkg_db \
        --sysconfdir /etc/pkg \
        --varbase /var \
        --full

the mk.conf used has

.ifdef BSD_PKG_MK       # begin pkgsrc settings

PKGSRC_COMPILER=        gcc

PKG_DBDIR=              /usr/pkg/pkg_db
LOCALBASE=              /usr/pkg
VARBASE=                /var
PKG_SYSCONFBASE=        /etc/pkg
PKG_TOOLS_BIN=          /usr/pkg/sbin
PKGMANDIR=              man

TOOLS_PLATFORM.install?=        /usr/pkg/bin/install-sh
TOOLS_PLATFORM.sh?=             /usr/pkg/bin/pdksh
TOOLS_PLATFORM.ksh?=            /usr/pkg/bin/pdksh
TOOLS_PLATFORM.awk?=            /usr/pkg/bin/nawk
TOOLS_PLATFORM.sed?=            /usr/pkg/bin/nbsed
TOOLS_PLATFORM.sh?=             /usr/bin/bash

PKGSRCDIR =             /misc/pkgsrc
DISTDIR =               /misc/pkg-distfiles
WRKOBJDIR =             /var/obj/pkgsrc
PACKAGES =              ${WRKOBJDIR}/packages

CLEANDEPENDS =          1
PKG_DEVELOPER =         1

.endif                  # end pkgsrc settings


and building pkgtools/digest results in

The usual search engines came up empty, with the exception of 
pkg/43372, which is similar, and still open.

Any ideas what to look for?

Cheerio,
