We don't have particular well tools for this, but I did the same dance
as the last time[1] to get the list of packages that build-depend on
ghc:
zcat ftp/dists/unstable/main/source/Sources.gz | \
grep-dctrl -e -ns Package -F Build-Depends '\<ghc\>' | \
sort -u > ~/rm-haskell-armel-sources
The packages that dak's reverse-dependency check then complains about
are:
dak rm -nR -p -B -a armel $(cat rm-haskell-armel-sources)
[...]
# Broken Depends:
darcsweb: darcsweb
fusionforge: fusionforge-plugin-scmdarcs
ganeti: ganeti
ganeti-htools
ghc-mod: ghc-mod-el
haskell-devscripts: haskell-devscripts
haskell-diagrams: libghc-diagrams-dev
libghc-diagrams-prof
haskell-platform: haskell-platform
haskell-platform-prof
m2l-pyqt: mediawiki2latexguipyqt
These are all arch:all, so breaking them should be okay. Note that
these become uninstallable and so do any armel packages that depend on
them (if such packages exist).
