The gs formula stopped working after libtiff was upgraded to 4.0.1.
It gives an error `no rule to make target obj/libtiff_.dev`.
Add the `--with-system-libtiff` flag so it compiles against 4.0.1.
Remove the `--disable-debug` flag, which is not a valid option.
Add deps on little-cms2 and jbig2dec and
Add `lcms2` and `jbig2dec` to the `renames` variable so that gs
will properly link against those two libraries that many people
already have installed who deal with images frequently. Without
those additions on systems with `lcms2` and `jbig2dec` installed,
`configure` will find them but not link correctly against them.
`autogen.sh` automatically calls configure and warns the user
that it is running configure with no args, explaining how to put
the args after `autogen.sh` if args are desired. Do that for
head builds. It is proper and saves configure from being run twice
when brewing head.

FixesHomebrew/homebrew#10559.
Also added missing deps for osm2pgsql.
Removed some ACLOCAL_FLAGS stuff as in theory this is not set in ENV.rb. Would like to see if it causes trouble. Should just work now.
Way back in the day, Homebrew defaulted to LLVM/-O3. A lot of stuff
failed to compile, and a lot of stuff just took forever with -O4.
We don't default this way anymore, and in fact use -Os per Apple
guidelines.
So remove these old "fixes" since they are no longer needed.
Fix Ghostscript build with system libpng 1.5 plus make it use system expat and
freetype2 and homebrew jasper and libtiff Do not try to use system freetype if
OS version is below 10.7

brewkit.rb changes ENV destructively, so lets not do that everytime a formula
is required. Now it's possible for other tools to require a formula
description without worrying about side-effects.
ClosesHomebrew/homebrew#56
If jpeg7 is already installed when you try to install ghostscript there is a
compilation error.
The answer is to move the included jpeg6 source directory out of the way,
download jpeg7, and create a link to the jpeg7 source inside of the
ghostscript source... ghostscript is none the wiser.
Specify dependencies in your formula's deps function. You can return an Array,
String or Hash, eg:
def deps
{ :optional => 'libogg', :required => %w[flac sdl], :recommended => 'cmake' }
end
Note currently the Hash is flattened and qualifications are ignored. If you
only return an Array or String, the qualification is assumed to be :required.
Other packaging systems have problems when it comes to packages requiring a
specific version of a package, or some patches that may not work well with
other software. With Homebrew we have some options:
1. If the formula is vanilla but an older version we can cherry-pick the old
version and install it in the Cellar in parallel, but just not symlink it
into /usr/local while forcing the formula that depends on it to link to
that one and not any other versions of it.
2. If the dependency requires patches then we shouldn't install this for use
by any other tools, (I guess this needs to be decided on a per-situation
basis). It can be installed into the parent formula's prefix, and not
symlinked into /usr/local. In this case the dependency's Formula
derivation should be saved in the parent formula's file (check git or
flac for an example of this).
Both the above can be done currently with hacks, so I'll flesh out a proper
way sometime this week.
