Imported from Debian bug http://bugs.debian.org/728630:

Source: smbc
Version: 1.2.2-3

Justification: FTBFS on amd64

Hi,

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

Debian now contains samba 4, which has header files in a special directory:
  /usr/include/samba-4.0/libsmbclient.h

Relevant part (hopefully):
> if x86_64-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../intl -DLOCALEDIR=\"/usr/share/locale\" -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -Wall -O3 -MT smbc-smbc.o -MD -MP -MF ".deps/smbc-smbc.Tpo" -c -o smbc-smbc.o `test -f 'smbc.c' || echo './'`smbc.c; \
> then mv -f ".deps/smbc-smbc.Tpo" ".deps/smbc-smbc.Po"; else rm -f ".deps/smbc-smbc.Tpo"; exit 1; fi
> smbc.c:34:26: fatal error: libsmbclient.h: No such file or directory

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.
