"base" isn't listed among the build-depends of the executable, so the 
obvious thing is to add base to the build-depends and see what happens then 
(might also be necessary for some other packages).

I'm not sure whether iterating that strategy will get lambdabot to build or 
it's too bit-rotted, so prepare to dive into the sources if you really want 
it to build.
