Please describe the problem.

Adding BUILDER=stack support in 441573a9 breaks building debian based packages.

What steps will reproduce the problem?

$ debian/rules clean
dh clean
        make -j1 clean
make[1]: Entering directory '/home/jtgeibel/repos/'
debian/cabal-wrapper clean
debian/cabal-wrapper: 14: debian/cabal-wrapper: cabal: not found
Makefile:101: recipe for target 'clean' failed
make[1]: *** [clean] Error 127
make[1]: Leaving directory '/home/jtgeibel/repos/'
dh_auto_clean: make -j1 clean returned exit code 2
debian/rules:12: recipe for target 'clean' failed
make: *** [clean] Error 2

What version of git-annex are you using? On what operating system?

6.20160114 (Ubuntu wily & trusty)

Please provide any additional information below.

I've patched this locally as follows. In the Makefile I've assumed that both cabal and stack support a clean command.

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

git-annex has been a great way for me to explore both Haskell and software packaging.

I enjoyed the interview on LWN.

I don't think this is a bug, I think build dependencies were not installed when building the package. done --Joey
