@ -1002,16 +1002,10 @@ sailing. Here are some known issues and things to try:
- **Do you have a new enough version of GHC ?** hledger supports GHC 6.10
and 6.12. Building with the `-fweb` flag requires 6.12 or greater.
- **Do you have a new enough version of cabal-install ?**
Recent versions tend to be better at resolving dependencies. The error
`setup: failed to parse output of 'ghc-pkg dump'` is another symptom of
this. To update, do:
$ cabal update
$ cabal install cabal-install
$ cabal clean
then try installing hledger again.
- **An error while building non-hledger packages.**
Resolve these problem packages one at a time. Eg, cabal install pkg1.
Look for the cause of the failure near the end of the output. If it's
not apparent, try again with `-v2` or `-v3` for more verbose output.
- **Could not run trhsx.**
You are installing with `-fweb610`, which needs to run the `trhsx` executable.

- **This package indirectly depends on multiple versions of the same package.**
You may have previously installed some of hledger's dependencies
depending on different versions of (eg) parsec. Then cabal install hledger gives
an error like this:
Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.

The above example could be resolved by, eg:
$ cabal install yesod --reinstall --constraint 'parsec == 3.1.0"
