Bug#845537: brp-pacu build-depends on obsolete package as first choice.

[peter green]

Package: brp-pacu
Version: 2.1.1+git20111020-5
Severity: serious

brp-pacu build-depends on libgtkdatabox-0.9.2-0-dev | libgtkdatabox-dev 
. Debian autobuilders only look at the first option.

libgtkdatabox-0.9.2-0-dev is now an obsolete package (no longer built by 
the libgtkdatabox source).

Please either remove the libgtkdatabox-0.9.2-0-dev option from the 
build-dependencies or reverse the order of the options and then check 
the package can be succesfully built/used with the new libgtkdatabox-dev.
