[jhc] How to compile new libraries from Hackage?

[Mark Wotton]

so I'm feeling a bit lost and lonely outside the comforting embrace of  
cabal-install.
I've read some of the discussions on this list, and I understand that  
it's not very practical to try to support Cabal as is, but what's the  
alternative method to compile libraries from Hackage? Where do the  
libraries go so jhc can find them? Is there a convention of some kind?

cheers
