Can you please apply the same fix to the Debian package?
Hello Till, Debian does not set LDFLAGS to "-Wl,-Bsymbolic-functions", as you can see by adding echo $$LDFLAGS before configure in debian/rules. Furthermore, use of libjpeg6b is deprecated since we are migrating to libjpeg8. In fact, hplip has already moved to libjpeg8 since you fixed the corresponding bug #634030 (thanks, by the way). So I am a bit confused by your report.
