Hi, Does anyone sees anything wrong with: ... $ cat debian/rules: VERSION = $(shell dpkg-parsechangelog | grep '^Version' | cut -d' ' -f2 | cut -f1 -d-) debian/tbb.pc: debian/tbb.pc.in sed -e"s/@VERSION@/$(VERSION)/g" $< > $@ build: debian/tbb.pc ... It used to work, but completely destroyed my latest upload of tbb in experimental: https://buildd.debian.org/status/fetch.php?pkg=tbb&arch=i386&ver=4.2~20130725-1.2~exp2&stamp=1378901879 Thanks for comments,
