[Haskell-cafe] Problems linking hsql-mysql

Hi Maciej,

I will try to reproduce the error -- could you send me your both *.cabal 
files (for hsql & hsql-mysql), if you have changed anything, and your 
system configuration.

Is this extremely urgent? I ask this, as these days exactly the end 
phase of the projects of about 100 beginner Haskell students, which I am 
the one to look after. So I am in a little of slow motion regarding 
other things... ;-)

But in case you are in emergency, please let me know... At first sight, 
I would say it looks like a configuration problem... ;-)
