ftbfs: E: fontconfig: alien-tag fc-cache-used-in-maintainer-script

[themusicgod1]

When trying to build from source using

debuild -us -uc -b

the result errors out with

Now running lintian fontconfig_2.13.1-4.4ubuntu1_amd64.changes ...
E: fontconfig: alien-tag fc-cache-used-in-maintainer-script [usr/share/lintian/overrides/fontconfig:1]
W: libfontconfig-doc: bad-whatis-entry [usr/share/man/man3/FcPatternIterNext.3.gz]

"This script apparently runs fc-cache. Updating of the fontconfig cache files is now handled automatically by triggers, so running fc-cache from maintainer scripts is no longer necessary."

lintian errors do not count as a build failure. You could file this as a bug in Debian if you like -- we'll pick up the fix from there in due course.
