tk: attempt to fix build on darwin

It complained about missing fontconfig symbols.
Also fix some white-space.
tk on darwin: another attempt to fix build

They add the -lfontconfig explicitly in macports, so hopefully it fixes it.

nixos/graphite-service: fix startup issue

The preStart snippets (graphite, carbon) try to create directories under
/var/db/. That currently fails because the code is run as user
"graphite". Fix by setting "PermissionsStartOnly = true" so that the
preStart stuff is run as 'root'.

Further:
 * graphite-web-0.9.12/bin/build-index.sh needs perl, so add it to PATH.
 * Now that preStart runs as root, we must wait with "chown graphite"
   until we're done creating files/directories.
 * Drop needless check for root (uid 0) before running chown.
nixos/grahite-service: mkdir -m => mkdir && chmod

mkdir -m will only set the permissions if it *creates* the directory.
Existing directories, with possibly wrong permissions, will not be
updated.

Use explicit chmod so permissions will always be correct.

libgnurl, a fork of libcurl used by GNUnet
gnunet: add libgnurl and GnuTLS as dependencies

libgnurl is essential for bootstrapping (needed to download a hostlist).
GnuTLS is needed by gnunet-gns-proxy.

Also sort dependencies alphabetically.
Shea told me composableDerivation is hard to understand.

Thus comment it and why it was written long time ago until it'll get replaced piecewise.
