well, the first and most immediate problem is that I can not even fetch the package from hackage using cabal: # cabal fetch plugins Resolving dependencies... cabal: dependencies conflict: ghc-6.10.1 requires process ==1.0.1.1 however process-1.0.1.1 was excluded because ghc-6.10.1 requires process ==1.0.1.0 so, although I believe the problem with different versions of the same package to co-exist on my computer may be ignored in mane cases, this case makes life very inconvenient. -- Valentyn On Feb 1, 2009, at 1:57 AM, Marc Weber wrote:

a) ignore it and hope you don't get segfaults or problems.
b) choose one process libraries and rebuild the other packages using that one.
About a) I'm not totally sure what could happen. I just can say That i've used different cabal versions and it went fine. I guess that the problem is
A using P-1.0 B using P-1.2
you using A and B, passing data indirectly from A to B and A and B having different compilation options or different behaviour. I'm not too sure about this. Maybe this can give you an idea what could happen. On the other hand you do use runXY or system from process only without passing data from one to the other so chances are good that your app will work nevertheless.
