Note that I package a number of dependencies that make no sense
outside of rackspace-novaclient. I don't want to pollute the main
namespace with those packages.
Before I was just grabbing the immediate dependencies. I _think_ this
will do the right thing by using the pre-existing setup hook to avoid
having to compute the transitive closure myself.
Some changes to be more idiomatic and use stdenv building blocks more.
I also added a `buildbot.withPlugins` instead of the current plugins
mechanism, which forces an unnecessary rebuild of the package and reruns
all the tests. This should be equivalent and more pleasant to use in
practice.
So the thinking is: anything that needs `haskell-gi-base` is going to
need `gobjectIntrospection` in order to work correctly; by adding this
one `buildDepends` (which therefore gets propagated), we put ourselves
in a position to simplify away a bunch of code in `cabal2nix`.
Firefox requires new version of the icu to build:
```
checking for icu-i18n >= 58.1... Requested 'icu-i18n >= 58.1' but version of icu-i18n is 57.1
configure: error: Library requirements (icu-i18n >= 58.1) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
```
Firefox requires the latest sqlite to build:
```
checking for sqlite3 >= 3.17.0... Requested 'sqlite3 >= 3.17.0' but version of SQLite is 3.16.2
configure: error: Library requirements (sqlite3 >= 3.17.0) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
```
mkDerivation doesn't do anything with this,
and while it does become an environment variable
AFAICT that was never the intention and isn't helpful here.
* Remove camlp4 dependency, no longer needed
* Keep pycaml to use ours over bundled version
* Enable tests for sanity (broken on darwin)
* no longer need to force specific ocaml version
* don't create python wrappers, they don't seem to be needed
* remove deprecated configure flag.
* fix spgen by removing bytecode version.
