xenkernel33 fails to compile

[Sean Bruno <seanbru%yahoo-inc.com@localhost>]

No idea what I'm doing wrong here, just updated and no luck on -current:

hile read what name hdr; do \
        /bin/sh 
/usr/pkgsrc/sysutils/xenkernel33/work/xen-3.3.2/xen/tools/get-fields.sh "$what" 
compat_$name $(echo compat/$hdr | sed 's,@arch@,x86_32,g') || exit $?; \
