To build the GTK version of NetSurf on a UNIX-like platform (although it has
only been tested on Debian, Ubuntu and FreeBSD), simply run "make" once you 
have got the relevent build dependencies installed.  Assuming you already
have GCC and GNU Make etc install, under a Debian-like OS, this should
suffice:

$ apt-get install libglade2-dev libcurl3-dev libxml2-dev libmng-dev 
$ apt-get install librsvg2-dev lemon re2c

Under Fedora, something like this:
$ yum install libglade2-devel curl-devel libxml2-devel libmng-devel
$ yum install librsvg2-devel lcms-devel re2c

If your distribution does not package lemon (like Fedora doesn't) then you'll
need to download it and build it yourself.  You may find it comes with the
SQLite packages (SQLite's parser is build with lemon).  If not, try this:

$ mkdir -p /usr/local/share/lemon
$ wget http://www.sqlite.org/cvstrac/getfile/sqlite/tool/lemon.c
$ wget -O /usr/local/share/lemon/lempar.c http://www.sqlite.org/cvstrac/getfile/sqlite/tool/lempar.c
$ sed -e's!lempar.c!/usr/local/share/lemon/lempar.c!' lemon.c > lem.c
$ gcc -o /usr/local/bin/lemon lem.c

NetSurf requires at minimum GTK 2.8.  Earlier versions will not work.  It
also depends on Cairo for rendering, but you should have this already with
versions of GTK 2.8 or later.

This will pull in loads of things, like all the GTK dev libraries, the PNG and
JPEG libraries, colour management libraries, zlib, OpenSSL etc that NetSurf
also depends on.

Type "make".  Currently, this produces a huge number of warnings, mostly due to
confused signedness.  These haven't been fixed yet but are mostly harmless.
Feel free to fix them and submit a patch.

Once built, NetSurf can be run by executing the shell script called "netsurf".
This script sets up some environment variables, which enables the NetSurf
binary to find its resources, making it easy to run the nsgtk binary from the
build tree.  If you're packaging NetSurf, you can edit the RESPATH macro near
the top of gtk/gtk_gui.c to point at a directory to search, removing much of
the need for this starter shell script (and the security implications it has).
