It seems that some warning inside scratchbox appears as error inside our autobuilder (this explain why the packages builds in your box and not into autobuilder) So it's no exactly a bug to be fixed.. I have fighted a lot with that trouble while packaging fltk: https://garage.maemo.org/builder/fre...log.FAILED.txt and solved here: https://garage.maemo.org/builder/fre...1.3.2-1maemo5/ Returning to your package, it seems it's missing "dh_makeshlibs" and i think you should upload it without /debian/*.shlibs. Feel free to take a look to the latest fltk build to check if there is something that can help.
