Well I'd say none of the packages I've tried, build out of the box,  
that include :


Agreed some of these compile right after tweeking the build-depends:  
and extensions: lines in the .cabal file
(apart from the pesky PatternSignatures which require a LANGUAGE  
pragma in the source file)

haskelldb-hdbc-sqlite3 is the one that I couldn't get past...

I didn't bother with hsql-mysql-1.7 since Duncan Coutts mentioned it  
required significant work (and I cannot do much)
