# ExtUtils::MakeMaker 6.42 of perl 5.10.0 makes "$(DISTVNAME).tar.gz" depend
# on "$(DISTVNAME)" distdir directory, which is always non-existent after a
# successful dist build, so the .tar.gz is always rebuilt.
#
# So although the .deb depends on the .tar.gz don't express that here or it
# rebuilds the .tar.gz every time.
#
# The right rule for the .tar.gz would be to depend on the files which go
# into it of course ...

# DISPLAY is unset for making a deb since under fakeroot gtk stuff may try
# to read config files like ~/.pangorc from root's home dir /root/.pangorc,
