[Haskell-cafe] can't build haxml under ghc 6.7, says HughesPJ is hidden... but ghc-pkg doesn't say it's hidden...

[Thomas Hartman]

Can I get some help building HaXml (from hackage) under ghc 6.7? 

I'm hoping to get HAppS running under 6.7, and use the new debugger to 
better understand what's going on under the hood. Eg, when I'm in the h 
function, I can take a look at the args and just see what types they are. 
(I am finding building an intuition from the documentation alone to be 
overwhelming. Too many types, too many instances... total confusion.) 
HaXMl is a dependendency for happs, that's why I need it.

Anyway building haxml this is what I get. The subject of my message more 
or less summarizes my confusion.
