[Haskell-beginners] cabal dependencies question

[Rob Nikander]

Hi,

I was unable to normally install the "mime" package -- I got an error
that it needed "base <= 4".  I have 4.3.1.0.  So I ran `cabal unpack
mime`, edited mime.cabal to say "base <= 4.3.1.0" and from that file's
directory ran `cabal install'.  It appeared to install it okay.   But
when I try to install another package that needs mime, I get the same
kind of error:

   > cabal install http-server
   Resolving dependencies...
   cabal: cannot configure mime-0.3.2. It requires base >=3 && <=4
   For the dependency on base >=3 && <=4 there are these packages: base-3.0.3.1
   and base-3.0.3.2. However none of them are available.
   base-3.0.3.1 was excluded because base-4.3.1.0 was selected instead

I'm wondering why it thinks the mime package wants base <= 4 when I
just installed with a .cabal file that says base <= 4.3.1.0.

??

thanks,
Rob
