[web-devel] Problem installing yesod-form 0.1.0

[Sven Koschnicke]

Hello,

today I tried to update to yesod 0.8, but cabal install fails at building yesod-form 0.1.0:

[3 of 8] Compiling Yesod.Form.Jquery ( Yesod/Form/Jquery.hs, dist/build/Yesod/Form/Jquery.o )
[4 of 8] Compiling Yesod.Form.Nic   ( Yesod/Form/Nic.hs, dist/build/Yesod/Form/Nic.o )
[5 of 8] Compiling Yesod.Form.Fields ( Yesod/Form/Fields.hs, dist/build/Yesod/Form/Fields.o )
[6 of 8] Compiling Yesod.Form.Class ( Yesod/Form/Class.hs, dist/build/Yesod/Form/Class.o )
[7 of 8] Compiling Yesod.Form       ( Yesod/Form.hs, dist/build/Yesod/Form.o )

cabal: Error: some packages failed to install:
yesod-0.8.0 depends on yesod-form-0.1.0 which failed to install.
yesod-auth-0.4.0 depends on yesod-form-0.1.0 which failed to install.
yesod-form-0.1.0 failed during the building phase. The exception was:
ExitFailure 1


I already tried to remove .cabal and .ghc, but a fresh install fails with the same error. I have ghc 7.0.2 running on macos 10.7
> cabal --version
cabal-install version 0.10.2
using version 1.10.1.0 of the Cabal library 

Thanks
