request-tracker4: FTBFS: "Can't locate Plack/Handler/Starlet.pm in @INC"

Imported from Debian bug http://bugs.debian.org/730641:

Package: request-tracker4
Severity: serious
Version: 4.0.17-2

Hello there,

I tried building your package, but it failed in a clean sbuild chroot:

> SOME DEPENDENCIES WERE MISSING.
> PSGI missing dependencies:
> Plack::Handler::Starlet ...MISSING
> Can't locate Plack/Handler/Starlet.pm in @INC (you may need to install the Plack::Handler::Starlet module) (@INC contains: /etc/perl /usr/local/lib/perl/5.18.1 /usr/local/share/perl/5.18.1 /usr/lib/perl5 /usr/share/perl5
> make[1]: *** [testdeps] Error 1
> make[1]: Leaving directory `/«PKGBUILDDIR»'
> make: [build-stamp] Error 2 (ignored)

This seems to be a case of a missing Build-Depends on the "starlet"
package. However, even with that added, I get test failures:
