audio/nas and noexec /tmp

[David Brownlee <abs%absd.org@localhost>]

Attempting to build audio/nas fails at the end of the configure stage with:

configure: creating ./config.status
config.status: creating config.h
=> Checking for portability problems in extracted files
mv -f Makefile Makefile.bak
imake -DUseInstalled -I/usr/pkg/lib/X11/config
sh: /tmp/imakeJ0i6c0: Permission denied
/var/obj/pkg/audio/nas/work/.tools/bin/imake: line 5: 21857 Aborted
             /usr/pkg/bin/imake -DBuildHtmlManPages=NO "$@"

mplayer has the following to address a similar issue:

# The configure script attempts to test-execute compiled programs in /tmp,
# but that directory may be mounted as noexec; work this around by setting
# TMPDIR to ${WRKDIR}
CONFIGURE_ENV+= TMPDIR=${WRKDIR:Q}

Does anyone have any thoughts on how to address this?
