Could you just comment on why / under what circumstances this is necessary, so
that I can add that to the commit message? (That'll increase the likelihood that
it doesn't get broken again by someone removing "unnecessary" dependencies.)

Hi,

The build will fail with the current version of boost in Debian (1.55),
ostensibly because of some changes in libboost starting with 1.50,
although I didn't run the issue all the way down to say for sure. There
are several similar references (same error message that I observed) out
there [1,2].

The other changes I needed to make to allow the tests to run were to add
"ant-optional" and "junit4" to the Build-Depends.

Cheers,
tony
