Via cabal:

--constraint='base<4'

or replace Control.Exception with Control.OldException

or add 'base < 4' to the depends in the .cabal file.

Thanks, Don.

Trying your first suggestion, I get the same result for the first and third method, and a ghc panic on cat_evals for the second method. All happening in ghc-6.10.3 installed via the Haskell Platform last week on OS X.

    bash-3.2$ cabal install lhs2tex --constraint='base<4'
    Resolving dependencies...
    [1 of 1] Compiling Main             ( /tmp/lhs2tex-1.1424460/lhs2tex-1.14/Setup.hs, /tmp/lhs2tex-1.1424460/lhs2tex-1.14/dist/setup/Main.o )

    cabal: Error: some packages failed to install:
    lhs2tex-1.14 failed during the configure step. The exception was:
    exit: ExitFailure 11

Still fishy about compiling Main first.

Now I'll edit add the '< 4' constraint on base, giving the same result:

    bash-3.2$ dirs
    ~/cabal
    bash-3.2$ cabal unpack lhs2tex
    Unpacking lhs2tex-1.14...
    bash-3.2$ cd lhs2tex-1.14

[lhs2tex.cabal edit happens here]

    bash-3.2$ cabal install
    Resolving dependencies...
    [1 of 1] Compiling Main             ( Setup.hs, dist/setup/Main.o )

    cabal: Error: some packages failed to install:
    lhs2tex-1.14 failed during the configure step. The exception was:
    exit: ExitFailure 11

Note that on linux, the package compiles without changing the base constraint. I don't know how.

Finally, use explicit ./configure & make:

Hm! Gremlins.

Via cabal:

--constraint='base<4'

or replace Control.Exception with Control.OldException

or add 'base < 4' to the depends in the .cabal file.
