[gentoo-user] Why ghc-bin is pulled in by portage update?

[gevisz]

I have dev-lang/ghc in my world file.

Today, while updating the system, the portage
wanted to update it. Ok. But why it pulles in
ghc-bin-7.8.4-amd64.tbz2?

# emerge --update --deep --with-bdeps=y --newuse --backtrack=90 --ask world

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     U  ] dev-lang/ghc-7.8.4 [7.6.3-r1]

Would you like to merge these packages? [Yes/No] y

Like all good language authors, the ghc authors wrote a lot of the
language and toolchain in Haskell, so you need a Haskell compiler to
compile ghc.

There is a 'ghcbootstrap' USE flag that you can set to use your locally
installed ghc to build the new ghc.

Ok. Thank you for information.
