Hi everyone,
one of the current Haskell release transitions blocker is the removal of
some obsolete Haskell libraries, in particular haskell-tls-extra
(https://bugs.debian.org/741230).
According to "dak rm -R -n haskell-tls-extra" this blocked by left over
packages depending on it on sparc. The root of the cause is a failure of
haskell-tls to build on sparc:
