Cabal compains about "Unknown build tool hasktags". It seems not necessary to set "Build-tools: hasktags" in cabal file?

cabal-install isn't capable of automatically building and installing build-tools for you.  So to install haskdogs, you need to do "cabal install hasktags && cabal install haskdogs".

I have installed hasktags, and .cabal/bin is in my PATH, i can run hasktags directly from shell. What else did i miss?

How did you specify your PATH?  You can't use ~/.cabal/bin, you need either $HOME/.cabal/bin or the fully expanded path.

It is $HOME/.cabal/bin , and `which hasktags' can find it without problem. Cabal 1.10.2, ghc 7.0.4, i'm trying to look into cabal source to find the problem.

Actually... looks like you're right.  I can't build it either, he appears to have hard-coded some paths in and it appears that you need some kind of magic to register a program as a build tool (that's what the error is from: hasktags isn't a registered build-tool).

Yes, I forgot to mention PATH. I expect somthing like export PATH="$HOME/.cabal/bin:$PATH" in .bash_profile or similar. Also, I probably should remove hasktags from the build-tools. Better check it's presense in tuntime. Thanks a lot, Sergey
