failed to install uuagc-cabal on OSX 10.6.8 about uhc HOT 7 OPEN

Have you done "cabal update" before this? Mtl-2.1.1 is available from hackage (http://hackage.haskell.org/package/mtl-2.1.1) and is the latest version, so I am not sure why it would not be able to satisfy that dependency.

And what if you run "cabal install mtl-2.1.1" first?

from uhc.

yes, I did cabal update before. and mtl-2.1.1 is there:

cabal install mtl-2.1.1
Resolving dependencies...
All the requested packages are already installed:
mtl-2.1.1
Use --reinstall if you want to reinstall anyway.

What is the output of running cabal install uuagc --reinstall -v ?

from uhc.

I successfully installed uuagc with cabal install uuagc --reinstall -v
however, ./configure still reports:

uuagc is available? : no
**** ERROR **** : uuagc must be installed, use (1) cabal+hackage, or (2) http://www.cs.uu.nl/wiki/HUT

I guess the configure script might be checking the wrong place for uuagc on OSX ?

from uhc.

I think you must have changed something in your installation, as the "-v" option should not have changed the behaviour of the install, only printing more debug information.

When uuagc is installed, it should be a binary in "~/.cabal/bin" named "uuagc". Please check that it exists. I guess that the cabal in directory is not in your path and that is why configure cannot find uuagc. There are two ways to fix this problem:

1. Add it to you path, so do something like export PATH="/Users//.cabal/bin:$PATH";
2. Tell configure where to find uuagc, by using ./configure --with-uuagc=/Users//.cabal/bin/uuagc

from uhc.

@gzmask could you confirm whether you still have this issue?

from uhc.

The solution of @jbransen fixes the problem. However, the installation directory has changes and is now in ~/Library/Haskell/bin (also pointed out in a text file named "where-is-my-stuff.txt" under ~/.cabal).
export PATH="$HOME/Library/Haskell/bin:$PATH" is the way to go, then ./configure works...
