Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

Relevant part (hopefully):
> /usr/bin/ld: warning: libicuuc.so.55, needed by /usr/lib/libmapnik.so, may conflict with libicuuc.so.57
> /usr/bin/ld: /usr/lib/libmapnik.so: undefined reference to symbol '_ZN6icu_5513UnicodeStringC1ERKS0_'
> //usr/lib/x86_64-linux-gnu/libicuuc.so.55: error adding symbols: DSO missing from command line
> collect2: error: ld returned 1 exit status

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
