[Pkg-haskell-maintainers] Bug#654856: darcs aborts with "Most RTS options are disabled. Link with -rtsopts to enable them."

[David Long]

Package: darcs
Version: 2.5.2-6
Severity: important

Dear Maintainer,

With this new version of darcs, I get a message

"darcs: Most RTS options are disabled. Link with -rtsopts to enable them."

whenever invoking darcs.  It doesn't matter what options I give to
darcs.  The version in stable (2.4.4-3) works fine.  From googling, I
gather this may have something to do with the ghc options used when
building darcs, but I can't figure out what it is that makes it break
on my installation.  Presumably if it broke on everyones, this bug
would have already been reported.  I have a pretty generic setup, with
testing as the default distribution and everything up-to-date.
