Compilation warning

[Jürgen Spitzmüller]

When compiling stable (probably also master), I am getting this:

[...]
%28LyXified%29.lyx examples/Example_%28raw%29.lyx examples/Welcome.lyx
templates/EPS_%28cropped%29.lyx templates/PDF_%28cropped%29.lyx
templates/README.new_templates; do \
	if  -q "^\\\\origin " "/usr/local/share/lyx/$i"; then \
		origin=`dirname "/systemlyxdir/$i"`/; \
		sed -e "s|^\\\\origin .*|\\\\origin $origin|" \
			"/usr/local/share/lyx/$i" >
"/usr/local/share/lyx/$i.tmp"; \
		mv -f "/usr/local/share/lyx/$i.tmp"
"/usr/local/share/lyx/$i"; \
		chmod 644 "/usr/local/share/lyx/$i"; \
	fi; \
done
/bin/sh: line 2: -q: command not found.
/bin/sh: line 2: -q: command not found.
[with many repetitions of this...]

If I understand the scrips correctly (which I very likely do not) the
command that is missing here is egrep.

However:

juergen at linux-9zah:~> which egrep
/usr/bin/egrep

Ideas?
