Taking a page from my software hygiene practices for pkgsrc (*) I
decided to work around this problem by fixing my build.sh wrapper script
to do this before it does anything else:

if [ -z "$MYBUILD_CLEAN" ]; then
	exec env -i USER=3D${USER} SHELL=3D/bin/ksh MYBUILD_CLEAN=3Dtrue "$0" ${1+=
"$@"}
fi

(fyi, my wrapper needs $USER internally to create the build directory
names as I like them)

This begs the question why build.sh doesn't do this itself (using the
shell it was invoked with somehow maybe).

(*) I've been using this patch (and precursors like it) in pkgsrc for a
very long time now:

-TOOLS_PLATFORM.env?=3D		/usr/bin/env
+TOOLS_PLATFORM.env?=3D		/usr/bin/env -i

It fixes all sorts of weird problems that you never knew you had before!
