Hi again.
I had another issue with optional syntax highlighting support in gitit. The gitit web site says that if it available in pandoc then it is available in gitit too.
Then the recommendation is: "To install gitit with highlighting support, first ensure that pandoc is compiled with highlighting support, then install gitit as above:
cabal install pandoc -fhighlighting --reinstall cabal install gitit"
If I do this it doesn't work because when installing gitit pandoc will be rebuilt again.
I did: cabal install git pandoc -fhighlighting --reinstall
which helped.
I guess this fits also in the explanations you gave me.
Yes, it's somewhat similar, and you did the right thing. If you request pandoc in isolation, it will be built against the versions of its dependencies you already have installed, or, if you don't, against the latest versions of these dependencies. However, gitit introduces additional constraints, and the version of pandoc you get when you ask for it individually currently doesn't meet these constraints. By putting them both as targets on a single command line, you get cabal to make a consistent install plan for both packages. Cheers, Andres
