GHC: double-conversion-0.2.0.1 unknown symbol

I'm trying to use the latest release of EclipseFP. Upon start, the scion-browser setup initializes, with everything going well until trying to install scion-browser-0.1. I get the following error in my Eclipse console:

...
Loading package double-conversion-0.2.0.1 ... linking ... ghc: /home/dpm/.cabal/lib/double-conversion-0.2.0.1/ghc-7.0.3/HSdouble-conversion-0.2.0.1.o: unknown symbol `_ZNK17double_conversion6Double5valueEv'
ghc: unable to load package `double-conversion-0.2.0.1'
cabal: Error: some packages failed to install:
scion-browser-0.1 failed during the building phase. The exception was:
ExitFailure 1

Apparently, ghc-pkg seems to think everything is OK with this package (ghc-pkg check prints nothing). Reinstalling double-conversion through cabal also changes nothing. Anybody any idea what's going on? I'm on Ubuntu 9.10 Linux, GHC 7.0.3 from the Haskell-Platform.

@n.m. Thanks, I didn't see that. – Dominic Mulligan
@n.m how did that question duplicate with this one? – Sawyer
@Sawyer: It looks like OP has undefined symbol _ZNK17double_conversion6Double5valueEv in HSdouble-conversion-0.2.0.*.o, exactly like I have. I conclude the two cases are identical. – n. 1.8e9-where's-my-share m.

As indicated here : close your eclipse and run this in your terminal:

cabal install blaze-textual --user -fnative --reinstall
cabal install aeson --user --reinstall

then, restart your eclipse.
